------------------------------------------------ An unknown substance has a volume of 2 cm\(^3\) and a mass of 38.6 grams. What is the density?

Answer :

Answer:

Density of the unknown substance, [tex]\rho=19.3\ g/cm^3[/tex]

Explanation:

It is given that,

Mass of the unknown substance, m = 38.6 g

Volume of the unknown substance, [tex]V=2\ cm^3[/tex]

We need to find the density of the unknown substance. The total mass per unit volume of a substance is called its density. Its formula is given by :

[tex]d=\dfrac{m}{V}[/tex]

[tex]d=\dfrac{38.6\ g}{2\ cm^3}[/tex]

[tex]d=19.3\ g/cm^3[/tex]

So, the density of the unknown substance is [tex]19.3\ g/cm^3[/tex]. Hence, this is the required solution.

density=mass/volume =38.6รท2=19.3
