What is the number of molecules in 2.24L of SO2 at STP?(a) 6.023*10^23(b) 6.023*10^22(c) 6.023*10^20(d) 6.023*10^21This question was addressed to me by my college professor while I was bunking the class.Query is from Kinetic Theory topic in chapter Kinetic Theory of Physics – Class 11

Answer»

The correct answer is (B) 6.023*10^22

Easiest explanation: ACCORDING to Avogadro’s LAW 22.4L of any GAS at STP is 6.023*10^23.

So, in 2.24L there will be 6.023*10^23/10

= 6.023*10^22.
