Question

A chemistry student needs of ethanolamine for an experiment. By consulting the CRC Handbook of Chemistry and Physics, the student discovers that the density of ethanolamine is . Calculate the mass of ethanolamine the student should weigh out. Round your answer to significant digits.

Answer 1

mass of ethanolamine 61.2 g

Step-by-step explanation:

Data:

V (Volume) = 60 mL

ρ (Density)= 1.02
`(g)/(cm^(3) )` = 1.02
`(g)/(mL)`

With the given data and using the density formula:

ρ =
`(mass)/(volume)`

It is possible to calculate the grams of ethanolamine that the student should weigh out. The mass in the formula is cleared and the data is replaced.

mass = ρ * volume

mass = 1.02
`(g)/(mL)` * 60 mL = 61.2 g of ethanolamine
