Question

Glycerol is a syrupy liquid often used in cosmetics and soaps. A 3.25-L sample of pure glycerol has a mass of 4.10 x 10 g.

What is the density of glycerol in g/cm"? Express your answer in grams per cubic centimeter.

Answer 1

Step-by-step explanation:

It is known that density is the amount of mass present in liter of solution or substance.

Mathematically, Density =
`(mass)/(volume)`

It is given that volume is 3.25 L and mass is
`4.10 * 10^(3) g`. Hence, calculate the density of glycerol as follows.

Density =
`(mass)/(volume)`

=
`(4.10 * 10^(3) g)/(3.25 L)`

=
`1.26 * 10^(3) g/L`

As, 1 L = 1000
`cm^(3)`.

So,
`1.26 * 10^(3) g/L * (1000 cm^(3))/(1 L)`

=
`1260 * 10^(6) g/cm^(3)`

Thus, we can conclude that the density of glycerol is
`1260 * 10^(6) g/cm^(3)`.
