A volume of 26.5 mL of nitrogen gas was collected in a tube at a temperature of 17° C and a pressure of 737 mm Hg. The next day the volume of the nitrogen was 27.1 mL with the barometer still reading 737 mm Hg. What was the temperature on the second day?

Answer 1

PV/T is constant, so you need T such that
27.1/T = 26.5/(273+17)

Answer 2

A volume of 75 L of nitrogen gas was collected in a tube at a temperature of 17c and a pressure of 737mmhg. The next day the volume of the nitrogen was 93L with the barometer still reading 737mmhg.what was the temperature on the second day?
