A student performed an experiment to determine the molecular weight of a gaseous compound.
Using the ideal gas law PV = nRT, and knowing the pressure, temperature, and volume of the vapor,
the student calculated the number of moles of gas, n, to be 0.0443 mol. The weight of the gas was
1.42 g. What is the molecular weight of this compound?
1 answer
mols = grams/molar mass. You know grams and mols, solve for molar mass.
