calculate moles of gas (11.2 / 44.0). This will be the value for n

Use PV = nRT and solve for V. The STP gives you the T and the P. Remember to use 0.08206 L-atm / mol-K for R.

Every gas occupies 22.4 liters per mole at STP

Convert your gas to moles by dividing the grams by the molecular mass. Then mulitply by 22.4 L/m to get the volume
