3. a liquid with a density of 8.1 g/ml occupies a volume of 30 ml. what is the mass of the liquid?
3. a liquid with a density of 8.1 g/ml occupies a volume of 30 ml. what is the mass of the liquid?
Answer
Explanation:
Step1: Recall density formula
The density formula is $\rho=\frac{m}{V}$, where $\rho$ is density, $m$ is mass and $V$ is volume. We can re - arrange it to solve for mass: $m = \rho\times V$.
Step2: Substitute given values
Given $\rho = 8.1\ g/mL$ and $V=30\ mL$. Then $m=8.1\ g/mL\times30\ mL$.
Step3: Calculate the mass
$m = 243\ g$.
Answer:
$243\ g$
