Answer: The mass of acetone is 22.61 g
Explanation:
To calculate mass of a substance, we use the equation:
[tex]\text{Density of substance}=\frac{\text{Mass of substance}}{\text{Volume of substance}}[/tex]
We are given:
Density of acetone = [tex]0.7857g/cm^3[/tex]
Volume of acetone = [tex]28.78mL=28.78cm^3[/tex] (Conversion factor: [tex]1cm^3=1mL[/tex] )
Putting values in above equation, we get:
[tex]0.7857g/cm^3=\frac{\text{Mass of acetone}}{28.78cm^3}\\\\\text{Mass of acetone}=22.61g[/tex]
Hence, the mass of acetone is 22.61 g
