The volume of a sample of hydrogen gas was decreased from 13.16 L to 6.45 L at constant temperature. If the final pressure exerted by the hydrogen gas sample was 7.73 atm, what pressure did the hydrogen gas exert before its volume was decreased?

Explanation:
Assuming ideal behavior, the gas sample should satisfy the Boyle's law, which states that
when temperature is held constant. [1]
In other words, the pressure the gas exerts is inversely related to the volume of the airtight container.
Therefore
Evaluate with
(rounded to three significant figures)
