Find volume of 1 mole of helium gas when the pressure is 1.46 atm and the temperature is 270k

We can use the ideal gas law equation to find the volume of He
PV = nRT
where P - pressure 1.46 atm x 101 325 Pa/atm = 147 934.5 Pa 
V - volume 
n - number of moles - 1 mol
R - universal gas constant - 8.314 Jmol⁻¹K⁻¹
T - temperature - 270 K
substituting these values in the equation
147 934.5 Pa x V = 1 mol x 8.314 Jmol⁻¹K⁻¹ x 270 K
V = 15.17 L
the volume is 15.17 L
