Use the general Gas Law, but be careful to use correct units!
p.V=n.R.T
so
n = [p.V] / [R.T]
in which:
- n = number of moles of any (ideal) gas (= 0.229 mole N2 when filled in)
- p = pressure in atm.
- V = volume in dm3
- T = absolute temperature in Kelvin (= oC + 273.15)
- R = general gasconstant = 0.08021 [atm.dm3.K-1.mol-1]
or = 8.314 [Pa.m3.K-1.mol-1] when SI-units are used.

How much space would 2.56 moles of xenon gas occupy at STP?
According to the ideal gas law, all gases occupy about 22.4 liters per moleof space at standard temperature and pressure, so 22.4x2.56=57.34 liters.
What is the pressure of 4 moles of helium in a 50 L tank of 308 K?
The pressure is 2,02 atmospheres.
How would a drop in pressure affect a gaseous system at?
the reaction would shift to favor the side with the most moles of gas
Would a drop in pressure affect a gaseous system at equilibrium?
the reaction would shift to favor the side with the most moles of gas. (apex).

At stp how many moles of helium would occupy 1.00l?
At standard temperature and pressure, 1 mole of any gas will occupy 22.4 liters. Set up a direct proportion of 22.4 liters/1 mole = 1 liter/x moles and solve for x. You get 0.045 moles.
