Determine the number of moles in a container of gas at STP with a volume of 99.2L

The number of moles of the gas in the container at STP is 4.43 moles

From the question,

We are to determine the number of moles of gas in a container at STP.

Using the ideal gas equation

PV =nRT

Where P is the pressure

V is the volume

n is the number of moles

R is the ideal gas constant (R = 0.08206 L atm mol⁻¹ K⁻¹)

and T is the temperature

From the given information

V = 99.2 L

and

At STP

P = 1 atm

T = 273 K

Putting the parameters into the formula, we get

∴

n = 4.4281 moles

∴ n = 4.43 moles

Hence, the number of moles of the gas in the container at STP is 4.43 moles

Explanation:

PV = nRT => n = PV/RT = (1 atm)(99.2L)/(0.08206 L Atm/mol K)(273K)= 4.43 mol
