Answer : The final pressure of gas is, 3.27 bar.

Explanation :

Boyle's Law : It is defined as the pressure of the gas is inversely proportional to the volume of the gas at constant temperature and number of moles.


P\propto (1)/(V)

or,


P_1V_1=P_2V_2

where,


P_1 = initial pressure = 4.94 bar


P_2 = final pressure = ?


V_1 = initial volume = 4.67 L


V_2 = final volume = 7.05 L

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


4.94bar* 4.67L=P_2* 7.05L


P_2=3.27bar

Therefore, the final pressure of gas is, 3.27 bar.
