Question

a 125-mL sample of liquid has a mass of 0.16kg. What is the density of the liquid with the proper number of significant figures?

Answer 1

The density of the liquid is 1.3 g/mL.

The mass of the liquid is 0.16 kg = 160 g.

The volume of the liquid is 125 mL.

Density = mass/volume = 160 g/125 mL = 1.3 g/mL

Answer 2

Answer : The density of sample of liquid is 1.28 g/mL

Explanation :

Density : It is defined as the mass contained per unit volume.

Formula used :

`Density=(Mass)/(Volume)`

Given :

Mass of sample of liquid = 0.16 kg = 160 g

conversion used : (1 kg = 1000 g)

Volume of sample of liquid = 125 mL

Now put all the given values in the above formula, we get:

`Density=(160g)/(125mL)=1.28g/mL`

Therefore, the density of sample of liquid is 1.28 g/mL
