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
