Question

Calculate the mass, volume and number of molecules of hydrogen and oxygen>>liberated on electrolysis of 72g of water at STP.​

Answer 1

Explanation:

18 g water contains N molecules

1. g contains N/18 ....

72 g contains N×72/18= 4 N

N =avogadro number 6.022×10^23

and STP volume will be 4× 22.4 L

= 89.6 L

no of H are( 4×2)N = 8N

no of O are (4×1)N = 4N
