Question

Convert a density of 7.2 g/ml into the unit kg/L

Answer 1

Unit conversion is a multi-step process, in which division or multiplication by a numeral factor is involved.

Density =
`7.2 g/mL` (given)

Since,
`1 g = 0.001 kg` and

`1 mL = 0.001 L`

Now, converting
`7.2 g/mL` to
`kg/L`:

`7.2 (g)/(mL)* (1 kg)/(1000 g)* (1000 mL)/(1 L)`

=
`7.2 kg/L`.

Hence, density is
`7.2 kg/L`.
