Molecular mass of cane sugar ( C 12 H 22 O 11) =12 × 12+22 × 1+11 × 16 =342 amu 1 mole of cane sugar ( C 12 H 22 O 11)=342 g (Molecular mass of cane sugar =342 g ) 342 g of cane sugar contain =6.022 × 1023 molecules

Q. Statement I : Molecular mass of cane sugar $(C_{12} H_{22} O_{11})$ is $182 am u$ .
Statement II : 1 mole of cane sugar contains $6.022 \times 1 0^{23}$ molecules of cane sugar.

Both statement I and II are correct.

Both statement I and II are incorrect.

Statement I is correct but statement II is incorrect.

Statement II is correct but statement I is incorrect.

Molecular mass of cane sugar $(C_{12} H_{22} O_{11})$
$= 12 \times 12 + 22 \times 1 + 11 \times 16$
$= 342 am u$
$1$ mole of cane sugar $(C_{12} H_{22} O_{11}) = 342 g$
(Molecular mass of cane sugar $= 342 g$ )
$342 g$ of cane sugar contain $= 6.022 \times 1 0^{23}$ molecules

Q. Statement I : Molecular mass of cane sugar (C12​H22​O11​) is 182amu. Statement II : 1 mole of cane sugar contains 6.022×1023 molecules of cane sugar.
