Question

50g watar is completely decomposed into hydrogen and oxygen .The total mass obtained will be

Answer 1

Answer:

Explanation:

Molar mass of water is 18 g/mol, 2 g from hydrogen, 16 from oxygen by weight,

so 50 x2/18 = 5.56 g H2, 44.44 g O2. However by volume, 2/3 of the total volume will be H2, 1/3 O2, about 62 .2 L total at STP.
