To find the number of molecules of naphthalene in a mothball, we can use the following steps:<\/p>\n\n\n\n
Step 1: Calculate the number of moles of naphthalene<\/h3>\n\n\n\n
We are given the mass of naphthalene as 6.000 g and its molar mass as 128.18 g\/mol. To calculate the number of moles of naphthalene, we use the formula:moles of naphthalene=mass of naphthalenemolar mass of naphthalene\\text{moles of naphthalene} = \\frac{\\text{mass of naphthalene}}{\\text{molar mass of naphthalene}}moles of naphthalene=molar mass of naphthalenemass of naphthalene\u200b<\/p>\n\n\n\n
Substituting the given values:moles of naphthalene=6.000\u2009g128.18\u2009g\/mol=0.04684\u2009mol\\text{moles of naphthalene} = \\frac{6.000 \\, \\text{g}}{128.18 \\, \\text{g\/mol}} = 0.04684 \\, \\text{mol}moles of naphthalene=128.18g\/mol6.000g\u200b=0.04684mol<\/p>\n\n\n\n
Step 2: Convert moles to molecules<\/h3>\n\n\n\n
Next, we use Avogadro’s number to convert moles to molecules. Avogadro’s number is 6.022\u00d710236.022 \\times 10^{23}6.022\u00d71023 molecules per mole. To find the number of molecules in 0.04684 moles of naphthalene, we multiply the moles by Avogadro’s number:number of molecules=0.04684\u2009mol\u00d76.022\u00d71023\u2009molecules\/mol\\text{number of molecules} = 0.04684 \\, \\text{mol} \\times 6.022 \\times 10^{23} \\, \\text{molecules\/mol}number of molecules=0.04684mol\u00d76.022\u00d71023molecules\/molnumber of molecules=2.82\u00d71022\u2009molecules\\text{number of molecules} = 2.82 \\times 10^{22} \\, \\text{molecules}number of molecules=2.82\u00d71022molecules<\/p>\n\n\n\n
Final Answer:<\/h3>\n\n\n\n
So, the number of molecules of naphthalene in a 6.000 g mothball is approximately 2.82\u00d710222.82 \\times 10^{22}2.82\u00d71022 molecules.<\/p>\n\n\n\n
This process shows how to go from mass to moles and then to molecules, using the molar mass of naphthalene and Avogadro’s number.<\/p>\n\n\n\n Naphthalene, C10H8, an ingredient in mothballs, has a molar mass of 128.18 g\/mol. How many molecules of naphthalene are in a mothball that has 6.000 g of naphthalene? The Correct Answer and Explanation is:1 To find the number of molecules of naphthalene in a mothball, we can use the following steps: Step 1: Calculate the […]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"default","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"footnotes":""},"categories":[25],"tags":[],"class_list":["post-262900","post","type-post","status-publish","format-standard","hentry","category-exams-certification"],"_links":{"self":[{"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/posts\/262900","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/comments?post=262900"}],"version-history":[{"count":0,"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/posts\/262900\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/media?parent=262900"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/categories?post=262900"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/tags?post=262900"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}![\"\"](\"https:\/\/learnexams.com\/blog\/wp-content\/uploads\/2025\/07\/learnexams-banner6-1258.jpeg\")
