To find its molar mass, we need to sum the molar masses of all the atoms in the formula:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Aluminum (Al)<\/strong>: The molar mass of aluminum is approximately 26.98 g\/mol.<\/li>\n\n\n\n<li><strong>Oxygen (O)<\/strong>: The molar mass of oxygen is approximately 16.00 g\/mol. Since there are three hydroxide (OH) groups, we have three oxygen atoms contributing to the molar mass:<br>[ 3 \\times 16.00 \\, \\text{g\/mol} = 48.00 \\, \\text{g\/mol} ]<\/li>\n\n\n\n<li><strong>Hydrogen (H)<\/strong>: The molar mass of hydrogen is approximately 1.01 g\/mol. Again, since there are three hydroxide groups, we have three hydrogen atoms:<br>[ 3 \\times 1.01 \\, \\text{g\/mol} = 3.03 \\, \\text{g\/mol} ]<\/li>\n<\/ul>\n\n\n\n<p>Adding these together gives us the molar mass of aluminum hydroxide:<\/p>\n\n\n\n<p>[<br>\\text{Molar mass of Al(OH)\u2083} = 26.98 \\, \\text{g\/mol} + 48.00 \\, \\text{g\/mol} + 3.03 \\, \\text{g\/mol} = 78.01 \\, \\text{g\/mol}<br>]<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 2: Calculate the Number of Moles<\/h3>\n\n\n\n<p>Now, we can calculate the number of moles of aluminum hydroxide in 98.3 grams:<\/p>\n\n\n\n<p>[<br>\\text{Number of moles} = \\frac{98.3 \\, \\text{g}}{78.01 \\, \\text{g\/mol}} \\approx 1.26 \\, \\text{moles}<br>]<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Conclusion<\/h3>\n\n\n\n<p>Thus, there are approximately <strong>1.26 moles<\/strong> of aluminum hydroxide in 98.3 grams. Understanding the concept of moles and molar mass is fundamental in chemistry, as it allows scientists to relate the mass of a substance to the number of particles it contains, facilitating calculations in chemical reactions, stoichiometry, and various applications in fields like biochemistry and materials science.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>How many moles are in 98.3 grams of aluminum hydroxide, Al(OH)3\u200b?
