Respuesta :

n / V = P / RT = (4.77 atm) / ((0.08205746 L atm/K mol) x (118 K)) = 0.4926 mol/L

(2.016 g/mol) x (0.4926 mol/L) = 0.993 g/L

Answer:

0.9926 g/L is the density of gas.

Explanation:

Molar mass of gas = M = 2.016 g/mol

Mass of  gas = m

Density of the gas = d =[tex]\frac{Mass}{Volume}=\frac{m}{V}[/tex]...(1)

Pressure of the gas = 4.77 atm

Temperature of the gas = T = 118 K

[tex]PV=nRT=\frac{m}{M}RT[/tex]

[tex]P=\frac{m}{V\times M}RT[/tex]

[tex]\frac{P\times M}{RT}=d[/tex]..(From (1))

[tex]d=\frac{4.77 atm\times 2.016 g/mol}{0.0821 atm l/mol K\times 118 K}[/tex]

d = 0.9926 g/L

0.9926 g/L is the density of gas.
