A chemistry student needs 10.0g of ethanolamine for an experiment. By consulting the CRC Handbook of Chemistry and Physics, the

iogann1982 [59]

Answer: The volume of ethanolamine the student should pour out is $9.80cm^3$

Explanation:

To calculate the volume of ethanolamine we use the equation:

$\text{Density of substance}=\frac{\text{Mass of substance}}{\text{Volume of substance}}$

Density of ethanolamine = $1.02g/cm^3$

Mass of ethanolamine = 10.0 g

Volume of ethanolamine = ?

Putting values in above equation, we get:

$1.02g/cm^3=\frac{10.0g}{\text{Volume of ethanolamine}}\\\\{\text{Volume of ethanolamine}=\frac{10.0g}{1.02g/cm^3}=9.80cm^3$

Thus the volume of ethanolamine the student should pour out is $9.80cm^3$
