Question

a. The volume of a sample of hydrogen gas was decreased from 14.24 L to 7.53 L at constant temperature. If the final pressure exerted by the hydrogen gas sample was 7.17 atm, what pressure did the hydrogen gas exert before its volume was decreased?

b.A sample of oxygen gas initially at 359 K was heated to 413 K. If the volume of the oxygen gas sample at 413 K is 640.2 mL, what was its volume at 359 K?

Answer 1

A)

Since 3.791 atm pressure, the hydrogen gas exert before its volume was decreased.

B)

Its volume at 359 K was 556.493 mL.
