Question #138342
Sulfur dioxide (SO2
), a gas that plays a central role in the formation of acid rain, is found in the exhaust of
automobiles and power plants. Consider a 1.53-L sample of gaseous SO2 at a pressure of 5.6x103 Pa. If the
pressure is changed to 1.5x104 Pa at a constant temperature, what will be the new volume of the gas?

Expert's answer
the temperature does not change. hence we do so on the basis of the Boyle Marriott law.
Boyle Marriott's law: the pressure of a gas at constant temperature is inversely proportional to its volume. that is,
P1 / P2 = V 2/ V1
where, P1 —is the initial pressure, P2 —is the next pressure, V1 —is the initial volume, and V2—is the next volume
according to the circumstances of the case
V1=1.53 L
P1=5.6*103 Pa
P2=1.5*104 Pa = 15*103 Pa
V2=?
V2=P1*V1/P2= 5.6*103* 1.53/15*103= 0.5712 L or 571.2 ml
ANSWER: 0.5712 L or 571.2ml
