If the pressure exerted on a 400 ml sample of hydrogen gas at constant temperature is increased from 1.5 atm to 5 atm, what will be the final volume of the sample?

Answer : The final volume of the sample of gas is, 120 mL

Explanation :

According to the Boyle's law, the pressure of the gas is inversely proportional to the volume of gas at constant temperature and moles of gas.

or,

where,

= initial pressure = 1.5 atm

= final pressure = 5 atm

= initial volume = 400 mL

= final volume = ?

Now put all the given values in the above formula, we get:

Therefore, the final volume of the sample of gas is, 120 mL
