A sample of nitrogen gas is stored in a 533.5 mL flask at 108 kPa and 10.0°C. The gas is transferred to a 750.0 mL flask at 29.1°C. What is the pressure of nitrogen in the second flask?

Question

A sample of nitrogen gas is stored in a 533.5 mL flask at 108 kPa and 10.0°C. The gas is transferred to a 750.0 mL flask at 29.1°C. What is the pressure of nitrogen in the second flask?

Answer 1

P1 = 108 kPa

V1 = 533.5 ml

T1 = 10ºC + 273 = 283K

P2 = ?

V2 =750 ml

T2 = 29.1 + 273 = 302.1

Combined Gas Law:

P1V1/T1 = P2V2/T2 and solving for P2, we have...

P2 = P1V1T2 / V2T1

plug in the above values and solve for P2 (units will be in kPa)
