Question

1. a liquid with a density of 8.1 g/ml occupies a volume of 30 ml. what is the mass of the liquid?

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 can re - arrange it to solve for mass: $m =
ho\times V$.

Step2: Substitute given values

Given $
ho = 8.1\ g/mL$ and $V=30\ mL$. Then $m=8.1\ g/mL\times30\ mL$.

Step3: Calculate the mass

$m = 243\ g$.

Answer:

$243\ g$
