Answer:

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
$4.94* 10^(-3)\ g/cm^3$ .
