Charles' law states that if pressure remains constant, the temperature and volume of a gas are directly proportional, so that as temperature increases, so does the volume. The equation for this law is:

"V"_1/"T"_1 = "V"_2/"T"_2

Given:
"T"_1 = "129K"
"V"_2 = "185L"
"T"_2 = "325K"

Solution:

Cross multiply.

"V"_1"T"_2 = "V"_2"T"_1

Solve for "V"_1.

"V"_1 = "V"_2"T"_1"/T"_2"

"V"_1" = ("185L")("129K")/"325K" = "73.4L"
