Calculate the molar mass of a compound in the Dumas method at `100^(@)C` for which volume of experimental container was 452 ml and the pressure was 745.1 torr. The difference in mass between the empty container and the final measurement was 1.129 gm.

`n=(PV)/(RT)=(745.1)/(760)xx(452xx10)/(0.0821xx373)=0.01448` mol
molar mass (M)`=(1.129)/(0.01448)=78.0` gm/mol
