Some Basic Concepts Of Chemistry Question 187

Question: The weight of a molecule of the compound $C_{60} H_{122}$ is [AIIMS 2000]

Options:

A) $1.4 \times 10^{- 21}$ g

B) $1.09 \times 10^{- 21}$ g

C) $5.025 \times 10^{23}$ g

D) $16.023 \times 10^{23}$ g

Show Answer

Answer:

Correct Answer: A

Solution:

Molecular weight of $C_{60} H_{122}$ $= 12 \times 60 + 122 \times 1$ $= 720 + 122 = 842$

$∵$ $6 \times 10^{23}$ molecule $C_{60} H_{122}$ has mass = 842gm
$∴$ 1 molecule $C_{60} H_{122}$ has mass $\frac{842}{6 \times 10^{23}}$ $= 140.333 \times 10^{- 23} g m$ $= 1.4 \times 10^{- 21} g m$ .
