Acetone is the main chemical in nail polish and has a density of 0.7857 g/mL. What is the volume of 6.54g of acetone ?

trapecia [35]

8.3mL

Explanation:

Given parameters:

Mass of acetone = 6.54g

Density of acetone = 0.7857 g/mL

Unknown:

Volume of acetone = ?

Solution:

Density is defined as the mass per unit volume of a substance. It is expressed mathematically as shown below:

Density = $\frac{Mass}{Volume}$

Since the unknown is volume, we make it the subject of the formula

Volume = $\frac{mass}{density}$

Input the values;

Volume = $\frac{6.54}{0.7857}$ = 8.3mL
