Some Basic Concepts Of Chemistry Question 32
Question: The number of molecules in 8.96 litre of a gas at $ 0{}^\circ C $ and 1 atm. pressure is approximately
Options:
A) $ 6.023\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:
[d] At S.T.P. 22.4 litre of gas contains $ 6.023\times 10^{23} $ molecules
$ \therefore $ molecules in 8.96 litre of gas $ =\frac{6.023\times 10^{23}\times 8.96}{22.4}=24.08\times 10^{22} $
