Answer: The new gas pressure will amount to 468.66 atm

Explanation:

Boyle's Law: This principle indicates that at constant temperature and amount of gas, the pressure and volume of the gas are inversely related.

$P\propto \frac{1}{V}$ (At a constant temperature and gas quantity)

or,

$P_1V_1=P_2V_2$

where,

$P_1$ = initial gas pressure = 74 atm

$P_2$ = final gas pressure =?

$V_1$ = initial gas volume = 190 ml

$V_2$ = final gas volume = 30 ml

Substituting all known values into the above equation results in the final or new pressure of the gas.

$74atm\times 190ml=P_2\times 30ml$

$P_2=468.66atm$

Hence, the new pressure of the gas will be, 468.66 atm

The gas's new pressure measures 467 atm. To determine this new pressure, we apply Boyle's Law. This law indicates that the pressure inversely correlates with the gas volume while maintaining a constant temperature. The law is expressed with the formula: where, are the initial pressure and volume, and are the final pressure and volume. The provided values allow us to substitute in the above formula, leading us to the conclusion that the gas's new pressure is 467 atm.
