Answer: The volume of the gas is 0.84 Liters

Explanation:

According to ideal gas equation:

[tex]PV=nRT[/tex]

P = pressure of gas = 1530 mm Hg = 2.01 atm     (760mmHg=1atm)

V = Volume of gas = ?

n = number of moles = 0.275

R = gas constant =[tex]0.0821Latm/Kmol[/tex]

T =temperature =[tex]75K[/tex]

[tex]V=\frac{nRT}{P}[/tex]

[tex]V=\frac{0.275atm\times 0.0820 Latm/K mol\times 75K}{2.01atm}=0.84L[/tex]

Thus the volume of the gas is 0.84 Liters
