Question

Calculate the density of unknown substance #1 which has a mass of 15.8 grams and a volume of 20 cm3. *

Answer 1

Answer:

$\boxed{\sf Density \ of \ unknown \ substance = 0.79 \ g/cm^3}$

Given:

Mass = 15.8 g

Volume = 20 cm³

To Find:

Density of unknown substance

Explanation:

Formula:

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

Substituting value of mass & volume in the formula:

$\sf \implies Density = \frac{15.8}{20} \\ \\ \sf \implies Density = 0.79 \: g/cm^3$
