Question

7.5 liters of a certain solution contain 37 grams of salt. What is the density of salt in the solution? Round your answer, if necessary, to the nearest tenth.

Answer 1

Answer:4.9

Explanation:

Answer 2

The density of salt solution is
`4.94* 10^(-3)\ g/cm^3`.

Explanation:

Given that,

Volume of certain solution, V = 7.5 litres

Mass of salt in solution, m = 37 grams

We know that,
`1\ L=1000\ cm^3`

We need to find the density of salt in the solution. The density of salt is given by mass per unit volume. The formula can be written as:

`d=(m)/(V)\\\\d=(37\ g)/(7.5* 10^3\ cm^3)\\\\d=4.94* 10^(-3)\ g/cm^3`

So, the density of salt solution is
`4.94* 10^(-3)\ g/cm^3`.
