Question

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?

Answer 1

Answer: The volume of the gas is 0.84 Liters

Step-by-step 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=(nRT)/(P)`

`V=(0.275atm* 0.0820 Latm/K mol* 75K)/(2.01atm)=0.84L`

Thus the volume of the gas is 0.84 Liters
