Determines the mass of an unknown gas to be 43 grams at 37


a. Determines the mass of an unknown gas to be .43 grams at 37 C as well as 720 mm Hg in a 250 mL container. Explain what is the molecular mass of the unknown gas? Use n=(PV/RT) but a little confused on where to proceed.

b. A gas is enclosed in a cylinder fitted with a piston. The volume of the gas is 1.50L at .86 atm. If the piston is moved to increase the gas pressure to 2.33 atm, explain what will the final volume be?
