the gaseous product of a reaction is collected in a 25.0L container at 27c. the pressure in the container is 300.0 kpa and the gas has a mass of 96.0g. what is the molar mass of the gas?

Answer 1

PV=nRT

PV= mass/molemass*RT
solve for mole mass. Watch the units for R, make certain they match your measurement units.
