Question: Which of the following is Loschmidt number
Options:
A) $ 6\times 10^{23} $
B) $ 2.69\times 10^{19} $
C) $ 3\times 10^{23} $

Show Answer
Answer:
Correct Answer: B
Solution:
The no. of molecules present in 1ml of gas at STP is known as Laschmidt number. 22400ml of gas has total no. of molecules $ =6.023\times 10^{23} $
1ml of gas has total no. of molecules $ =\frac{6.023\times 10^{23}}{22400} $
$ =2.69\times 10^{19} $ .
