Question

What is the volume in milliliters of 7.26 g of acetone? (Acetone has a density of 0.7857 g/cm^3)

Answer 1

Density = $\frac{MASS}{VOLUME}$

∴ $Volume = \frac{MASS}{DENSITY}$
               
                 =  $\frac{7.26 g}{0.7857 g / cm^{3} }$  
                
                 =  9.24 cm³

Since 1 cm³ = 1 ml
Then the volume in ml would be  9.24 ml

Answer 2

Answer: The volume of acetone is 9.24 mL

Explanation:

To calculate mass of a substance, we use the equation:

$\text{Density of substance}=\frac{\text{Mass of substance}}{\text{Volume of substance}}$

We are given:

Density of acetone = $0.7857g/cm^3=0.7857g/mL$    (Conversion factor:  $1cm^3=1mL$  )

Mass of acetone = 7.26 g

Putting values in above equation, we get:

$0.7857g/mL=\frac{7.26g}{\text{Volume of acetone}}\\\\\text{Volume of acetone}=9.24mL$

Hence, the volume of acetone is 9.24 mL
