If you use three significant figures for the molar mass of propane (44.1 g/mole), then you get the same answer as I, i.e. 49.0 g (to 3 sig. figs.)

Thanks J.R S., I have corrected the 49.1g to 49.0g. Correct sig. figs. are very important, as an incorrect sig. fig. can leave a bad taste in your mouth, Joe.
