calculate the molar mass of an unknown whose mass was 0.846 g, and occupied a volume of 354 cm3 at a pressure of 752 torr and a temperature of 100 degrees celcius.
I came up with .0114 moles, I want to know if this is correct.

yes and no. Yes, n = number of moles = 0.0114 but that isn't the molar mass which is the question.
n = grams/molar mass will get that for you if you solve for molar mass.
