Recall the ideal gas law equation:
P , pressure = 895 torr
n , number of moles, unknown
V , volume = 8.7 L
R, gas constant =
** Values for the gas constant can be found online or in textbooks
T, temperature in K, but given: T = 24°C
To solve for grams of Cl2, we need to do these steps:
Chlorine is widely used to purify municipal water supplies and to treat swimming pool water. Suppose that the volume of a particular sample of Cl2 gas is 8.70 L at 895 torr and 24 oC.
How many grams of Cl2 are in the sample?
