Molar Volume of Gases Q

[luken93]

31. After a 2.60 L container weighing 500.00 g is filled
with butane gas it weighs 506.31 g. The gas was
stored at a temperature of 20.0°C and a pressure of
102 kPa. Calculate the molar mass of butane gas.

You have V, P, T and R

use PV=nRT to find n

Then you have n and m

Find Mr?

Oh woops, didn't realise haha
V = 2.60   P = 102   n = x   T = 293   R = 8.31















Mr = 57.9 g mol ^-1



How silly of me, it was staring me right in the face hahaha
