pV = nRT

where,

p = pressure (in atm)

V = volume (in dm³)

n = no. of moles (mol.)

R = molar gas constant, (0.082atm.dm³.mol⁻¹.K⁻¹)

T = absolute temperature (Kelvin)

making V the subject of the formular,

V =

n = 4mol.

R = 0.082atm.dm³.mol⁻¹.K⁻¹

T = (-23 + 273)K = 250K

P = 300mmHg = atm

V =

V =
