For hydrogen gas
a)cv=5R/2 b)cp=5R/2
C)cv is negligible
d)cp-cv=1.99cal\mol k
Ans is a =16b.

yadvirsingh: Relation between specific heats per unit mass:

cp−cv=rcp−cv=RM

Hence, r=RM

Here, M is molecular weight.

Hydrogen:

cp−cv=a
a=RM =R2

Oxygen:

cp−cv=b
b=RM =R32

Ratio of a and b:

ab=(R/2)(R/32) =16a = 16b
