HI Mandy,

1) our equation is C + 2H2 ---> CH4

2 mol H2 gives 1 mol of CH4

This means, from the given table of molar mass,

4 gm hydrogen gives 16 gm CH4

So, for 16 gm CH4 , 4 gm hydrogen is required.

Hence, for 153 .2 gm CH4, hydrogen needed will be,

(153.2×4)/16 = 38.3 gm hydrogen is needed.

2) As per given equation,

6 moles of HNO3 gives 2 moles of H2O

It means,

6×63=378 gm HNO3 gives 2 ×18 = 36 gm of H2O.

So,

147.3 gm HNO3 will give = (147.3)×(36)/378 = 14.03 gm H2O

Thus, convert 14.03 gm of H2O into moles

Moles of H2O = 14.03/18 = 0.8 mol
