Answer:
Explanation:
Here in this reaction we use weight-weight relationship concept i.e
8moles CO reacts with 17 moles of H2 then 6.5 moles of CO react with
6.5×(17/8) moles of H2 i.e 13.8 moles of H2. weight of H2 required is 13.8* molar mass of H2
=2*13.8 = 27.6g
Weight of H2 required is 27.6 gr
