The empirical formula is the simplest whole-number ratio of the elements in the compound, and the molecular formula is the actual number of atoms of each element in the compound.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 1: Calculate the molar mass of the empirical formula.<\/h3>\n\n\n\n<p>The empirical formula is <strong>C\u2083H\u2083O<\/strong>. To find its molar mass, we sum the atomic masses of each element in the empirical formula:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Carbon (C) has an atomic mass of approximately 12 g\/mol.<\/li>\n\n\n\n<li>Hydrogen (H) has an atomic mass of approximately 1 g\/mol.<\/li>\n\n\n\n<li>Oxygen (O) has an atomic mass of approximately 16 g\/mol.<\/li>\n<\/ul>\n\n\n\n<p>Thus, the molar mass of <strong>C\u2083H\u2083O<\/strong> is:<br>[<br>3 \\times 12 \\, \\text{g\/mol} + 3 \\times 1 \\, \\text{g\/mol} + 1 \\times 16 \\, \\text{g\/mol} = 36 + 3 + 16 = 55 \\, \\text{g\/mol}<br>]<br>So, the molar mass of the empirical formula is <strong>55 g\/mol<\/strong>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 2: Compare the molar mass of the empirical formula to the given molar mass.<\/h3>\n\n\n\n<p>The problem gives the molar mass as <strong>110 g\/mol<\/strong>. To find how many times the empirical formula fits into the molecular formula, divide the molar mass of the molecular compound by the molar mass of the empirical formula:<br>[<br>\\frac{110 \\, \\text{g\/mol}}{55 \\, \\text{g\/mol}} = 2<br>]<br>This means that the molecular formula is twice the empirical formula.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 3: Multiply the empirical formula by 2.<\/h3>\n\n\n\n<p>To obtain the molecular formula, multiply each element in the empirical formula by 2:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Carbon: ( 3 \\times 2 = 6 )<\/li>\n\n\n\n<li>Hydrogen: ( 3 \\times 2 = 6 )<\/li>\n\n\n\n<li>Oxygen: ( 1 \\times 2 = 2 )<\/li>\n<\/ul>\n\n\n\n<p>Thus, the molecular formula is <strong>C\u2086H\u2086O\u2082<\/strong>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 4: Identify the correct answer.<\/h3>\n\n\n\n<p>The molecular formula <strong>C\u2086H\u2086O\u2082<\/strong> corresponds to option <strong>A<\/strong>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Final Answer:<\/h3>\n\n\n\n<p>The correct answer is <strong>A.
