using this equation: Ni+H2SO4=H2+NiSO4
how many liters of hydrogen gas at 298degK and 2.5atm could be produced if you react 25 grams of nickel metal?

Follow the steps in this example, then use PV = nRT to calculate volume.

I ended up getting 4.21L of H2 is that right?
The steps I took were
25gNi/58.6934=.43mol Ni
v=(.43)x(0.0821x1atm/molK)x(298K)/2.5atm=4.21L H2?
this doesn't look right...
