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)

Atoms in $1$ molecule of $C_{12}{H}_{22}{O}_{11}$
$=12+22+11=45$
$\therefore$ Atom in $1$ mole $=45\times N_A$
$=45\times 6.02\times 10^{23}$ atoms/mole
