Question

How many atoms are contained in one mole of sucrose $\left(C_{12}H_{22}O_{11}\right)$?

• A. $45 \times 6.02 \times 10^{23}$ atoms/mole
• B. $5 \times 6.62 \times 10^{23}$ atoms/mole
• C. $5 \times 6.02 \times 10^{23}$ atoms/mole
• D. None of these

Answer 1

Answer: (A)

1 mole of sucrose contains $6.023 \times 10^{23}$ molecules
$\because$ 1 molecule of sucrose has $45$ atoms
$\therefore 6.023 \times 10^{23}$ molecule of sucrose has $45 \times 6.023 \times 10^{23}$ atoms/mole
