Question

mercury is a shiny liquid. calculate its density if 1417.5 g of the substance occupies 105. ml. be sure your answer has the correct number of significant figures.

Explanation:

Step1: Recall density formula

Density $
ho=\frac{m}{V}$, where $m$ is mass and $V$ is volume.

Step2: Substitute given values

Given $m = 1417.5$ g and $V=105$ mL. So $
ho=\frac{1417.5}{105}$.

Step3: Calculate density

$
ho=\frac{1417.5}{105}=13.5$ g/mL (rounded to three - significant figures as 105 has three significant figures).

Answer:

$13.5$ g/mL
