the pressure that water exerts when gas is collected by water displacement
vapor pressure
When collecting gas by water displacement you have to __________ the given vapor pressure from the pressure given to obtain the pressure of the dry gas alone. Once you do this, plug the new pressure number in your formula
subtract
The only gas law which needs Liters in the formula is the
ideal gas (pv = nrt)
