Text Solution

Verified by Experts

1 mole of any gas occupies 22400 cc of volume 1 mole of any gas contains 6.023x x `10^(23)` molecules
:. 22400 cc of gas at STP contains 6.023 xx `10^(23)` molecules
1.12 xx `10^(-7)`cc of gas at STP contains ___________ ?
`(1.12 xx 10^(-7)xx6.023xx10^(23))/(22400)=3.015l xx 10^(12)`" molecules".
