A1.00-l sample of carbon tetrachloride has a mass of 1.58 kg. what is the density of this substance in g/cm3?

1.58gcm⁻³

Explanation:

Given parameters:

Volume of sample = 1.00L

Mass of sample = 1.58kg

unknown:

Density of the sample

Solution:

The density of a substance is expressed as its mass per unit volume.

The units of the parameters are given for volume as liters and for mass as kg.

We need to convert to cm³ for volume and into g for the mass:

        1L = 1000cm³:

        Therefore, the volume of the sample is 1000cm³

For the mass:

           1kg = 1000g

           1.58kg gives 1.58 x 1000g = 1580g

The density of the sample will be:

               Density  =

               Density = = 1.58gcm⁻³
