Chapter 1, Problem 2ASA

Finding the density of an unknown liquid.

Having obtained the volume of the flask, the student emptied the flask, dried it, and filled it with an unknown liquid whose density she wished to determine. The mass of the stoppered flask when completely filled with liquid was $57.418\text{g}$. Find the density of the liquid.

a. First we need to find the mass of the liquid by measuring the difference:

$\text{Mass}\text{of}\text{liquid }= \_\_\_\_\_ \text{g}-\_\_\_\_\_\_\_ \text{g}=\_\_\_\_\_\_ \text{g}$

b. Since the volume of the liquid equals that of the flask, we know both the mass and volume of the liquid and can easily find its density using the equation in lb. Make the calculation.

$\text{Density}\text{of}\text{liquid}=\_\_\_\_\_\_\text{g}/\text{mL}$
