Verified step by step guidance1
Identify the chemical formula of sucrose, which is \( \text{C}_{12}\text{H}_{22}\text{O}_{11} \).
Determine the atomic masses of carbon (C), hydrogen (H), and oxygen (O) from the periodic table. Typically, \( \text{C} \) is approximately 12.01 g/mol, \( \text{H} \) is approximately 1.01 g/mol, and \( \text{O} \) is approximately 16.00 g/mol.
Calculate the total mass contributed by carbon atoms: \( 12 \times 12.01 \) g/mol.
Calculate the total mass contributed by hydrogen atoms: \( 22 \times 1.01 \) g/mol.
Calculate the total mass contributed by oxygen atoms: \( 11 \times 16.00 \) g/mol. Add these values together to find the molar mass of sucrose.
