An object weighing 90 n has a volume of 45 ml and a mass of 0.9 g. what is its density?

The density of object is 0.02 g/mL.

Explanation:

Density:

Density is equal to the mass of substance divided by its volume.

Units:

SI unit of density is Kg/m3.

Other units are given below,

g/cm3, g/mL , kg/L

Formula:

D=m/v

D= density

m=mass

V=volume

Symbol:

The symbol used for density is called rho. It is represented by ρ. However letter D can also be used to represent the density.

Given data:

mass of object = 0.9 g

Volume of object = 45 mL

density = ?

Solution:

d = m/v

d = 0.9 g/ 45 mL

d = 0.02 g/mL.
