# What is the volume of a solution that has a specific gravity of 1.2 and a mass of 185 g?

$154 m l$

#### Explanation:

1. Find the density of the solution by the formula:
$s p . g r a v i t y = \left(\rho \text{ solution")/(rho " water at } {4}^{o} C\right)$
2. Rearrange the formula;
rho " solution"=(sp. gravity)(rho " water at " 4^oC)
where:
$\rho \text{ water at " 4^oC=1 "g/ml}$
3. Plug in values to find density of solution to the formula in step 2;
rho " solution"=(1.2)(1 "g/ml")
rho " solution"=1.2"g/ml")
4. To find the volume:
$V = \frac{m}{\rho}$, plug in values
V=(185cancelg)/(1.2cancel(g)/"ml"
5. The $V = 154 m l$
