The molar mass is 53.56 g/mol.
What is molar mass?
The molar mass of a substance is the mass of the substance which contains one mole of a substance.
Given data:
Given volume of flask = V = 247.3 mL = 0.2473 L
Temperature = T = 100 = 373 K
Pressure of the gas = P = 745 mmHg = 0.9802 atm
Mass of acetone = 0.424 g
R= 0.0821 L.atm [tex]mol^-^1[/tex][tex]K^-^1[/tex]
Assuming the molar mass of acetone to be M g/mol
The ideal gas equation is shown below:
PV=nRT
[tex]PV=\frac{mass}{M} RT[/tex]
Putting all the above data.
M= 53.56 g/mol
Hence, the molar mass is 53.56 g/mol.
