Question

a thermometer contains 5.00×10⁻¹ ml (0.5 ml) of mercury and mercury has a density of 13.59 g/ml. what is the mass of mercury?

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 we can re - arrange it to $m =
ho\times V$.

Step2: Identify given values

We are given that $
ho=13.59\ g/mL$ and $V = 5.00\times10^{- 1}\ mL=0.5\ mL$.

Step3: Calculate mass

Substitute the values into the formula $m=
ho\times V$. So $m=(13.59\ g/mL)\times(0.5\ mL)=6.795\ g$.

Answer:

$6.795\ g$
