Do you want answer in grams or in liters? If the answer has to be in liters, it will be at STP.

The following reaction is for electrolysis of water.

2H2O = 2H2+O2

Hence, 2(1*2+16)= 36 gm of water is converted into 2(1*2) or 4 gms hydrogen and 2*16 = 32 gms of oxygen.

1 gallon of water = 3785.411 gms.

Hence, hydrogen produced = (4/36)*3785.411 gm = 420.60gms

The volume of 2 gm of hydrogen is 22.4 liters at STP.

Hence, hydrogen produced = 420.60*22.4/2 = 4710.72 liters at STP.

36 gm of water produces 32 gms of oxygen.

Hence, oxygen produced = (32/36)*3785.411 gm = 3364.81gms

The volume of 32 gm of oxygen is 22.4 liters at STP.

Hence, oxygen produced =3364.81*22.4/32 = 2355.367 liters at STP.

Kindly ACCEPT the answer. BONUS and POSITIVE feedback will be appreciated.
