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
