Question

An unknown substance has a volume of 2 cm and a mass of 38.6 grams what is the density

Answer 1

density=mass/volume =38.6÷2=19.3

Answer 2

Density of the unknown substance,
`\rho=19.3\ g/cm^3`

Step-by-step explanation:

It is given that,

Mass of the unknown substance, m = 38.6 g

Volume of the unknown substance,
`V=2\ cm^3`

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 :

`d=(m)/(V)`

`d=(38.6\ g)/(2\ cm^3)`

`d=19.3\ g/cm^3`

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