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
