If I have 0.275 moles of gas at a temperature of 75 K and a pressure of 1530 mmHg, what is the volume of the gas?
Maru [420]

Answer: The volume of the gas is 0.84 Liters

Explanation:

According to ideal gas equation:

PV=nRT

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 =0.0821Latm/Kmol

T =temperature =75K

V=\frac{nRT}{P}

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

Thus the volume of the gas is 0.84 Liters
