Ideal Gas Law

What is the pressure in atmospheres exerted by a 0.500 mol sample of nitrogen gas in a 10.0 L container at 298 K?

If the pressure exerted by 0.325 mol of hydrogen gas is 2.01 atm at 35°C, what is the volume? (Hint: convert temperature)

A gas sample occupies 8.77 L at 3.98 atm. What is the temperature, in Kelvin, given that there are 1.45 mol of gas in the sample? (Hint: convert temperature)

A 4.44 L container holds 15.4 g of oxygen at 22.55°C. What is the pressure? (Hint: convert to moles and Kelvin)

A tank of hydrogen gas has a volume of 22.9 L at 14.3 atm and 12°C. How many moles of the gas is inside the tank? (Hint: convert temperature)
