How many moles of nitrogen gas are in a flask with a volume of 0.25 L at a pressure of 2.96 atm and a temperature of 300 K

The number of moles of nitrogen gas is 0.030 moles

Explanation:

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

where,

P = pressure of the nitrogen gas = 2.96 atm

V = Volume of the gas = 0.25 L

T = Temperature of the gas = 300 K

R = Gas constant =

n = number of moles of nitrogen gas = ?

Putting values in above equation, we get:

Hence, the number of moles of nitrogen gas is 0.030 moles
