We use old Boyle's Law..........
Explanation:
........which holds that
And thus
Explanation:
To solve this, we can use the pressurevolume relationship of gases, illustrated by Boyle's law:
We're asked to find the original pressure exerted by the gas, so let's rearrange to solve for

#V_1 = 250# #"mL"# (original volume) 
#P_2 = 5# #"atm"# (final pressure) 
#V_2 = 500# #"mL"# (final volume)
Let's plug in these values into the equation to find the original pressure:
Thus, the original pressure of the gas was
We can check this answer by plugging all the values into the original equation:
Our answer is furthermore correct!
As per Boyle's law the answer is
Explanation:
Boyle's law states that if the pressure of a gas changes from p1 to p2 then the volume would also change from v1 to v2 at a constant temperature. The pressure is also inversely proportional to the volume
