Question

A sample of gas occupies 36.1 L at standard temperature and pressure (STP, 0.00 0C and 1.00 atm). What is the volume of this gas, in L, at 757 torr and 26.0 0C?

Answer 1

STp conditions
volume         V1 = 36.1L
tempetature    T1 = 273K
pressure       P1 = 1 atm = 760 torr

Experimetal conditions
volume        V2 =
pressure       P2 = 757 torr
temperature    T2 = 26C⁰ = 26+ 273 = 299K

P1V1/T1    = P2V2/T2
V2         = P1V1T2/P2T1
           = 760*36.1*299/757*273
           = 8203364/206661
           = 39.7L
volume is 39.7 L
