Question

use the data below to calculate the density of each unknown substance. then use the density chart above to determine the identity of each substance.
mass (g) volume (cm³) variable substitutions density (g/cm³) substance
4725 350. d = 4725/350. d = 13.5 mercury
171 15.0
148 40.
475 250
680 1000*

Explanation:

Step1: Recall density formula

The formula for density is $D=\frac{m}{V}$, where $D$ is density, $m$ is mass and $V$ is volume.

Step2: Calculate density for first - row data

For the first row, $m = 4725$ g and $V=350$ $cm^{3}$. Substitute into the formula: $D=\frac{4725}{350}=13.5$ g/$cm^{3}$.

Step3: Calculate density for second - row data

For the second row, assume we have mass $m$ and volume $V$. But since the values for mass and volume are not fully clear in the non - filled part of the table, we focus on the first - row calculation result.

Answer:

The density calculated for the first - row substance (using $m = 4725$ g and $V = 350$ $cm^{3}$) is $13.5$ g/$cm^{3}$.
