Answer to Question #167069 in General Chemistry for Nada

Question

An unknown gas at 77.1 

∘

C

 and 1.05 atm

 has a molar mass of 44.10 g/mol.

 Assuming ideal behavior, what is the density of the gas?

Answer 1

We have given,

Temperature, T = $77.1^{\circ} C$ =$350.1K$

Pressure, P = $1.05$ atm

Molar Mass, $M = 44.10 g/mol$

Let the density of gas be d

Using the Ideal gas equation,

$PV = nRT$

$1.05\times V = \dfrac{m}{44.10}\times 8.314\times 350.1$

$\dfrac{m}{V} = \dfrac{46.305}{2910.73}$

$d = 0.0159g/mol$
