= 0.02414 g/L
Using the formula;
PV = nRT, where P is the pressure, V is the volume, n is the number of moles , T is the temperature and R is the gas constant, 0.08206 L. atm. mol⁻¹.
But; PV = nRT = P/RT =n/V and n = mass/molar mass
Thus;
P/RT = n/V = (Mass/molar mass)/V
Therefore; (P/RT)× molar mass = mass/V = density
Thus;
Density = (0.76 × 2.015 g/mol)/ (0.08206 ×773.15 K)
= 0.02414 g/L
