5. a 15.0 g - sample of a liquid has a density of 0.875 g/ml. a. what is the volume, in milliliters, of the…

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 volume and mass.

Step2: Solve for volume in part a

Given $m = 15.0\ g$ and $\rho=0.875\ g/mL$. Using $V=\frac{m}{\rho}$, we substitute the values: $V=\frac{15.0\ g}{0.875\ g/mL}$. $V=\frac{15.0}{0.875}\ mL\approx17.1\ mL$

Step3: Solve for mass in part b

Given $V = 34.6\ mL$ and $\rho = 0.875\ g/mL$. Using $m=\rho V$, we substitute the values: $m=0.875\ g/mL\times34.6\ mL$. $m = 0.875\times34.6\ g=30.3\ g$

Answer:

a. $17.1\ mL$ b. $30.3\ g$
