Combined Gas Law
Combines Charles's law, Boyle's law, and Gay-Lussac's law.
1. Write the combined gas law equation (take out the unmentioned or unneeded unit- temperature):P1V1 / T1 = P2V2 / T2P1V1 = P2V2
2. and solve for V2:
P1V1 / P2 = V2
3. Insert the appropriate values in their proper places on the right-hand side of the above equation and carry out the necessary operations.
-Be sure to convert all the temperature to Kelvin. (+273)
V2 =(0.755 atm)(4.31 L) / (1.25 atm) = 2.60 L
