A chemistry student needs 10.0g of ethanolamine for an experiment. By consulting the CRC Handbook of Chemistry and Physics, the student discovers that the density of ethanolamine is ·1.02gcm−3. Calculate the volume of ethanolamine the student should pour out.

The volume of ethanolamine the student should pour out is

Explanation:

To calculate the volume of ethanolamine we use the equation:

Density of ethanolamine =

Mass of ethanolamine = 10.0 g

Volume of ethanolamine = ?

Putting values in above equation, we get:

Thus the volume of ethanolamine the student should pour out is

c is the answer because when something is left after something evaporates that shows the chemical change.
