hey here is ypour answer

1. 2g of H2
no. of moles = 2/2 = 1 = Na avagadro no.)

2. 4g of N2
no. of moles = 4/28 = 1/7 = 0.14= 0.14Na avagadro no.)

3. 8g of O2
no. of moles = 8/32 = 1/4 = 0.25 = 0.25Na avagadro no.)

4. 16g of CO2
no. of moles = 16/44 = 4/11 = 0.36 =0.36Na(avagadro no.)

so, lowest no. of molecules is contained by 2) 4g of N2.

hope it helps
have a good day ☺
