Question

Hey chemistry student needs 35.0 mL of chloroform for an experiment. I consulting the CRC handbook of chemistry and physics, the student discovers that the density of chloroform is 1.48 g/cm ^-3. Calculate the mass of the chloroform the student should way out. Be sure you answer it has the correct number of significant digits

Answer 1

We have the density of chloroform which is 1.48 g/cm^3 and the volume required which is 35.0 mL.

To find the mass, we apply the following formula:

$mass=\text{density}\cdot\text{volume,}$

But you should know that cubic centimeters (cm^3) are the same that milliliters (mL).

Doing the calculations, we obtain that:

$\text{mass}=1.48\frac{g}{\operatorname{cm}^3}\cdot35.0cm^3=51.80\text{ g.}$

The mass of chloroform is 51.8 grams.
