Question

The question is: .33 moles of H2 gas at 135 kPa and 14.2 degrees Celsius would occupy a volume of how many Liters?

What equation would I use to solve this?

Answer 1

I don't remember the name of the equation but you would use:

PV=nRt
pressure(volume)=# of moles(8.31 L*kpa/K*mol)(temp)
so your formula should look like:
135 kpa(v)=.33(8.31)(287.2K)
(I got the temp by adding 273 to the degrees celsius)
