PV = nRT

Use the Ideal Gas Law equation to solve each problem. The ideal gas law equation is:
PV = nRT
where: P = pressure
V = volume
n = # of moles of given gas
R = universal gas constant
T = temperature
Volume must be in Liters
Temperature must be in Kelvin
Pressure must be in atm or kPa
If mass of the gas is given, convert to moles
using molar masses
R = 0.0821 atm L / mol K
or 8.314 kPa L / mol K
Choose the appropriate “R” value based on
the units given for pressure
It is not safe to put aerosol canisters in a campfire, because the pressure inside the canister gets very high and
they can explode. If I have a 1.0 liter canister that holds 2.0 moles of a gas, and the campfire temperature is
1400oC, what is the pressure inside the can?
How many moles of gas are in a 30.0 liter scuba canister if the temperature of the canister is 300.0 K and the
pressure is 200.0 atmospheres?
3. On a warm day, a 2.20 liter balloon is filled with 0.800 g of helium. The pressure in the balloon is 2.25 atm. What
is the temperature on this day?
4. A camping stove uses a tank that holds 3000.0 g of propane gas (C3H8). What volume tank is needed to hold the
gas at 25°C and a pressure of 3.0 atm?
