Question

À container's filled with 28 liters of argon gas at a temperature of 353 K. If the gas is

held at 4.9 atm of pressure, how many moles of the gas are in the container?

Answer 1

Answer: 4.74 moles of gas are in the container.

Step-by-step explanation:

1. Use the ideal gas law. PV = nRT. and re-arrange from moles by divided RT on both sides.

2.You should get the following equation:
`n=PV/RT`

3.Insert values:
`n = PV/RT = ((4.9 atm)(28 L))/((0.082 (L*atm)/(K*mol)*(353K)) = 4.74 moles.`

4.There are 4.74 moles in the container.

Good luck with chemistry!
