A sample of gas at 25°C has a volume of 11 L and exerts a pressure of 0.868 atm. How many moles
of gas are there? (R=.0821L atm/mol K)

The number of moles of gas present are 0.390 moles

Explanation:

To calculate the number of moles of gas, we use the equation given by ideal gas which follows:

where,

P = pressure of the gas = 0.868 atm

V = Volume of the gas = 11 L

T = Temperature of the gas =

R = Gas constant =

n = number of moles of gas = ?

Putting values in above equation, we get:

Hence, the number of moles of gas present are 0.390 moles
