Question: The number of molecule at NTP in 1 ml of an ideal gas will be
Options:
A) $ 6\times 10^{23} $
B) $ 2.69\times 10^{19} $
C) $ 2.69\times 10^{23} $
D) None of these

Answer:
Correct Answer: B
Solution:
$ \because $ 22400 ml at NTP has $ 6.023\times 10^{23} $ molecule
$ \therefore $ 1 ml at NTP has = $ \frac{6.023\times 10^{23}}{22400} $
= $ 0.0002688\times 10^{23} $ $ =2.69\times 10^{19} $ .
