Answer:
455 Torr
Explanation:
To get the correct answer, we employ the use of the General gas equation.
In its general form, the General gas equation can be written as:
P1V1/T1 = P2V2/T2
Defining the parameters;
P1 = 764 torr
V1 = 8.6L
T1 = 45 degrees Celsius = 273.15+ 45 = 318.15K
P2 = ?
V2 = 13.3L
T2 = 20 degrees Celsius = 273.15 + 20 = 293.15K
Rearranging the equation yields: P2 = P1V1T2/T1V2
Substituting the values:
P2 = (764 * 8.6 * 293.15)/(318.15 * 13.3)
P2= 455.2 Torr
