Solution

To find the molar mass of sucrose (C12H22O11), we need to add up the molar masses of all the atoms in the formula.

  1. Carbon (C) has a molar mass of 12 g/mol. Since there are 12 carbon atoms in sucrose, the total mass contributed by carbon is 12 g/mol * 12 = 144 g/mol.

  2. Hydrogen (H) has a molar mass of 1 g/mol. Since there are 22 hydrogen atoms in sucrose, the total mass contributed by hydrogen is 1 g/mol * 22 = 22 g/mol.

  3. Oxygen (O) has a molar mass of 16 g/mol. Since there are 11 oxygen atoms in sucrose, the total mass contributed by oxygen is 16 g/mol * 11 = 176 g/mol.

Adding these up, the molar mass of sucrose is 144 g/mol + 22 g/mol + 176 g/mol = 342 g/mol.

So, one mole of sucrose contains 342 grams of sucrose. The correct answer is 342 g.
