Answer : The pressure at this new altitude is, 364.2 mmHg

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 \frac{1}{V}

or,

P_1V_1=P_2V_2

where,

P_1 = initial pressure = 760 mmHg

P_2 = final pressure = ?

V_1 = initial volume = 62.3 L

V_2 = final volume = 130 L

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

760mmHg\times 62.3L=P_2\times 130L

P_2=364.2mmHg

Thus, the pressure at this new altitude is, 364.2 mmHg
