Volume of Acetone = 28.56ml
Mass in grams = ?
For the density of Acetone which has Propanone in IUPAC names, we will find that density is 0.7925g/cm3. This is the same as 0.7925g/ml.
Now by using the formula
Density = Mass / Volume
Mass = Density x Volume
Putting the values of density and volume in formula,
Mass = 0.7925g/ml x 28.56ml
Mass = 22.63g
so the mass is 22.63g
