Question

if 1 gm of each of the following gases are taken at STP which of the gases will occupy the greatest and smallest volume? gases are CO, CH4, H2O, NO​

Answer 1

Answer:

Explanation:

Volume of gas = 22.4 / molecular mass

CO --> volume = 22.4/ 28

CH4 --> volume = 22.4/ 16

H2O --> volume =22.4/ 18

NO --> volume = 22.4/ 30

We don't have to solve this

Simply check the denominator ...one with the lowest denominator has greatest volume

Therefore

Gas with Greatest volume= CH4

gas with least volume = NO
