Volume of gas- 8.352 mL
Pressure- 742 mm Hg
Temperature - 99 Celsius (372 Kelvin)
Mass of Condensed Liquid- .0326 g.
What is molar mass?
I know the equation is Molar Mass= Mass RT/ VP, but what is it when you plug everything in.?

convert pressure to atm and temperature to kelvin u get:
mw=(.0326)(.08206)(372)/(.008352)(.9763)
=122.04

I solve these using the Avogadro volume: one mole of an ideal gas occupies 22.4 liters at STP. Using that, we have: 0.008352/22.4 = 760/742 x 372/273 x M, where M is the number of moles. Solve for M, and divide it into 0.0326 grams to get the answer.

2 NO + Br2 > 2NOBr Kp = P(NOBr)2 / { P(NO) P(Br2)2 } resolve for the Kp utilising the 1st set of information, and then use that Kp to unravel for the unknown partial rigidity in the 2d set.

8.352mL x 742mm/760mm x 273K/372K x 1mol/22400mL = 2.671 x 10^-4 mole
(0.0326g)/(2.671x10^-4mol) = 122g/mole
