Some Basic Concepts Of Chemistry Question 203

Question: Volume of a gas at STP is $1.12 \times 10^{- 7}$ cc. Calculate the number of molecules in it [BHU 1997]

Options:

A) $3.01 \times 10^{20}$

B) $3.01 \times 10^{12}$

C) $3.01 \times 10^{23}$

D) $3.01 \times 10^{24}$

Show Answer

Answer:

Correct Answer: B

Solution:

$∵$ 22400cc of gas at STP has $6 \times 10^{23}$ molecules
$∴$ 1.12 $\times 10^{- 7}$ of gas at STP has $\frac{6 \times 10^{23} \times 1.12 \times 10^{- 7}}{22400}$ $= .03 \times 10^{14} = 3 \times 10^{12}$ .
