Answer:

There are 0.311 moles of  gas in the tank

Explanation:

Complete question

A 4.00g sample of gas is found to exert a pressure of 1.71 atm when confined in 3.60L container at a temperature of 241 K. Find the number of moles of the gas

Solution

As we know

[tex]PV = nRT[/tex]

where P is the pressure of the gas in atm

V is the volume in liters

n is the number of moles

R is the gas constant = 0.08206 L·atm/K·mol

and T is the temperature in Kelvin

Substituting the given values in above equation, we get -

[tex]1.71 * 3.60 = n * 0.08206 * 241\\n = 0.311[/tex]

There are 0.311 moles of  gas in the tank
