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
