I have hydrogen in a 12 L tank, at T=15 C. Some of it is used, the T = const. and Δp=0.4 MPa,

the molar mass of hydrogen is M=2*10^-3 J/(mol*K). Find the mass of the used hydrogen.

2. Relevant equations

Am I wrong in simply using:

[itex]\Delta m=\frac{M}{RT}V\Delta p[/itex] ?

That gives roughly 4 kg's..

Thanks,

U.
