Question

Round this answer to 2 decimal places, please. 5) If I have 0.275 moles of gas at a temperature of 75 K and a pressure of 1330 mm Hg, what is the volume of the gas? NOTE: The gas constant, R, equals 62.36 mmHg ∙ L/mol∙K

Answer 1

The volume of the gas is 0.97 L

Explanation:

According to ideal gas equation:

$PV=nRT$

P = pressure of gas = 1330 mm Hg

V = Volume of gas = ?

n = number of moles = 0.275

R = gas constant =$62.36mmHgL/Kmol$

T =temperature =$75K$

$V=\frac{nRT}{P}$

$V=\frac{0.275mol\times 62.36mmHgL/K mol\times 75K}{1330mmHg}=0.97L$

Thus the volume of the gas is 0.97 L
