Question

what is the volume in milliliters of 6.74g of acetone? if the density of acetone is 0.7857g/cm^3

Answer 1

$m=6,74g\\ d=0,7857\frac{g}{mL}\\\\ V=\frac{m}{d}=\frac{6,74g}{0,7857\frac{g}{mL}}\approx8,58mL$

Answer 2

Answer: The volume of acetone is 8.58 ml

Explanation:

To calculate volume 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 = $0.7857g/cm^3$

mass of acetone = 6.74 g

Volume of acetone = ?  

Putting values in above equation, we get:

$0.7857g/cm^3=\frac{6.74g}{Volume}$

Volume of acetone=$8.58cm^3=8.58ml$    $1cm^3=1mL$  

Hence, the volume of acetone is 8.58 ml.
