Answer:
28 L
Explanation:
Assuming the temperature of the gas is constant, we can solve the problem by applying Boyle's law, which states that the product between the pressure of the gas (P) and its volume (V) remains constant:
\(PV=const.\)
\(P_1 V_1 = P_2 V_2\)
where
\(P_1 = 700.0 mm Hg\) is the initial pressure
\(P_2 = 99 mm Hg\) is the final pressure
\(V_1 = 4.0 L\) is the initial volume
\(V_2 = ?\) is the final volume
Re-arranging the equation, we can find the final volume:
\(V_2 = \frac{P_1 V_1}{P_2}=\frac{(700.0 mmHg)(4.0 L)}{99 mmHg}=28.0 L\)
