What is the molar volume of a gas at standard temperature and pressure?

The molar volume of any gas at standard pressure and standard temperature is 22.4 liters per mole.

Explanation:The ideal gas law is PV=nRT

P is pressure and if we consider standard pressure, then we have 1.00 atm.

V is volume and that is what we are trying to solve.

n is the number of moles, which is 1.00 moles since we are trying to determine the volume of a gas in one mole.

R is the ideal gas constant which equals

0.0821 (Liters x atmospheres)/(mole x kelvin)

T is the standard temperature which is 273 kelvin.

Rearrange the equation to solve for volume.

V = nRT/P

V = (1.00 mol)(0.0821 L atm/mol K)(273 K)/ 1.00 atm

V = 22.4 L

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons

they are all solids.
