Question

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

• 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)

$45 \times 6.02 \times 10^{23}$ atoms/mole

Answer 2

Atoms in $1$ molecule of $C_{12}H_{22}O_{11}$ $=12+22+11=45$ $\therefore$ Atom in $1$ mole $=45 \times N_{A}$ $=45\times 6.02\times10^{23}$ atoms/mole
