Question

1. calculate the mass of a substance that has a known density of 83.2 kg/l in a solution of 17.9 l

5 points

Explanation:

Step1: Recall density formula

The density formula is $
ho=\frac{m}{V}$, where $
ho$ is density, $m$ is mass and $V$ is volume. We need to solve for $m$, so $m =
ho\times V$.

Step2: Substitute given values

Given $
ho = 83.2$ kg/L and $V=17.9$ L. Then $m=83.2\times17.9$.
$m = 83.2\times17.9=1489.28$ kg

Answer:

1489.28 kg
