Question

The weight of one molecule of a compound C 60 H 122 is (A) 1.2 × 10-20 g (B) 5.025 × 1023 g (C) 1.4 × 10-21 g (D) 6.023 × 1023 g

The molecular weight of C 60 H 122=60 × 12+122=720+122=842 The weight of one molecule of C 60 H 122 = molecular wt. of compound/Avogadro number =(842/6.023 × 1023) =1.4 × 10-21 g

Q. The weight of one molecule of a compound $C_{60} H_{122}$ is

$1.2 \times 1 0^{- 20} g$

$5.025 \times 1 0^{23} g$

$1.4 \times 1 0^{- 21} g$

$6.023 \times 1 0^{23} g$

The molecular weight of
$C_{60} H_{122} = 60 \times 12 + 122 = 720 + 122 = 842$
The weight of one molecule of $C_{60} H_{122}$
$=$ molecular wt. of compound/Avogadro number
$= \frac{842}{6.023 \times 1 0 ^{23}}$
$= 1.4 \times 1 0^{- 21} g$
