The volume of hydrogen gas at 38.0°C and 763 torr that can be produced by the reaction of 4.33 g of zinc with excess sulfuric acid is __________ L.
Any idea? It's not at STP, so I don't know... What I got is
4.33/65.39 = .066 = moles of zinc.
The mole ratio of H2 to Zinc in the reaction is 1:1, so there is .066 moles of hydrogen. And at STP, 1 mole of gas occupies 22.4 L. But it's not at STP... so idk...
I think I may have figured it out... PV=nRT...
