Some Basic Concepts Of Chemistry Question 206

Question: The number of molecules in $ 8.96\ L $ of a gas at $ 0^{o}C $ and 1 atmosphere pressure is approximately [BHU 1993]

Options:

A) $ 6.02\times 10^{23} $

B) $ 12.04\times 10^{23} $

C) $ 18.06\times 10^{23} $

D) $ 24.08\times 10^{22} $

Show Answer

Answer:

Correct Answer: D

Solution:

$ \because $ 22.4L of a gas at STP has no. of molecules $ =6.023\times 10^{23} $

$ \therefore $ 8.96L of a gas at STP has no. of molecules $ =\frac{6.02\times 10^{23}\times 8.96}{22.4} $ $ =2.408\times 10^{23} $ $ =24.08\times 10^{22} $ .
