Use PV = nRT
Calculate n = number of moles of gas.
Then mols = g/molar mass
You know moles from the above calculation, you know grams (flask + gas - flask), solve for molar mass.
in a lab experiment to obtain the molar mass of a voltaile liquid, the following data is obtained:
volume of flask=225ml
mass of flask=77.834gms
mass of flask+gas=78.416gms
temperature=100 degrees celsius
pressure=714 torr
What is the molar mass of the liquid?
A)11.1 g/mol
B)22.6 g/mol
C)84.3 g/mol
D)99.2 g/mol
please help with working out this problem.
