A gas is at a pressure of 12.5psi and a volume of 750mL. What volume will the gas occupy at a pressure of 18psi?

520.8 mL

Explanation:

We can solve this problem by using Boyle's Law, which states that:

"For a fixed mass of an ideal gas kept at constant temperature, the pressure of the gas is inversely proportional to its volume"

Mathematically:

where

p is the pressure

V is the volume

We can rewrite the equation as

where here:

is the initial pressure of the gas

is the initial volume

is the final pressure

And solving for V2, we find the final volume of the gas:
