Let\u2019s assume the mass of isopropanol in the container is provided.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. <strong>Calculate the molar mass of isopropanol (C3H8O)<\/strong><\/h3>\n\n\n\n<p>Isopropanol has the following chemical formula: C3H8O. To find its molar mass, you need to sum the atomic masses of all the atoms in one molecule of isopropanol:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Carbon (C): 12.01 g\/mol (3 atoms) = 12.01 \u00d7 3 = 36.03 g\/mol<\/li>\n\n\n\n<li>Hydrogen (H): 1.008 g\/mol (8 atoms) = 1.008 \u00d7 8 = 8.064 g\/mol<\/li>\n\n\n\n<li>Oxygen (O): 16.00 g\/mol (1 atom) = 16.00 g\/mol<\/li>\n<\/ul>\n\n\n\n<p>Now, sum these values to get the molar mass of isopropanol: Molar&nbsp;Mass&nbsp;of&nbsp;Isopropanol=36.03+8.064+16.00=60.094\u2009g\/mol\\text{Molar Mass of Isopropanol} = 36.03 + 8.064 + 16.00 = 60.094 \\, \\text{g\/mol}<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. <strong>Use the formula to calculate moles<\/strong><\/h3>\n\n\n\n<p>To find the number of moles, use the following formula: Moles=Mass&nbsp;(g)Molar&nbsp;Mass&nbsp;(g\/mol)\\text{Moles} = \\frac{\\text{Mass (g)}}{\\text{Molar Mass (g\/mol)}}<\/p>\n\n\n\n<p>If you know the mass of isopropanol, just divide that number by 60.094 g\/mol. For example, if there are 120 grams of isopropanol in the container, the calculation would be: Moles=12060.094\u22481.998\u2009moles\\text{Moles} = \\frac{120}{60.094} \\approx 1.998 \\, \\text{moles}<\/p>\n\n\n\n<p>Thus, there would be approximately 2 moles of isopropanol in the container.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Conclusion<\/h3>\n\n\n\n<p>To determine the exact number of moles of isopropanol in the container, you need the mass of the isopropanol and the molar mass (which is 60.094 g\/mol). Divide the mass of the isopropanol by its molar mass to get the number of moles.
