A gas that has a pressure of 2 atm and a volume of 10 L. What would be the new volume if the pressure was changed to 1 atm? Choose the correct formula to solve the problem.

P₁/T₁= P₂/T₂

P₁V₁ = P₂V₂

V₁/n₁ = V₂/n₂

PV = nRT

A sample of a gas has a volume of 852 mL at 298 K. What temperature is necessary for the gas to have a volume of 945 mL? Choose the formula you would use to solve the problem.

P_t = P₁ + P₂ + P₃ + ...

P₁V₁ = P₂V₂

V₁/T₁ = V₂/T₂

P₁V₁/T₁ = P₂V₂/T₂

A sample of a gas has a volume of 852 mL at 298 K. What temperature is necessary for the gas to have a volume of 945 mL? Choose the formula used to solve the problem.

P_t = P₁ + P₂ + P₃ + ...

P₁V₁ = P₂V₂

V₁/T₁ = V₂/T₂

P₁V₁/T₁ = P₂V₂/T₂

If a nitrogen gas occupies a volume of 500 ml at a pressure of 0.971atm. What volume will the gas occupy at a pressure of 1.50 atm?

P₁V₁ = P₂V₂

PV = nRT

P₁/T₁ = P₂/T₂

V₁/n₁ = V₂/n₂

Determine the number of moles in a container of gas at STP with a volume of 99.2 L. Which formula is used?

V₁/n₁ = V₂/n₂
