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 10^3 g.
what is the density of glycerol in g/cm^3?

The density of glycerol will be

Explanation:

Density is defined as the mass contained per unit volume.

Given : Mass of glycerol= g

Volume of bromine =  3.25 L=  

Putting in the values we get:

Thus density of glycerol will be

The density of glycerol used in cosmetics and soaps is 1.26 g/cm³.

FURTHER EXPLANATION

Density is the measure of the compactness of a material. It is the mass per given volume. This can be expressed mathematically as:

 (equation 1)

To solve the problem, we first sort the given in the problem:

mass = 4.10 × 10³ g

volume - 3.25 L

The problem is asking for the density in units of g/cm³ which means that we must first convert the volume from liters to cm³.

Now we can plug in the values of mass and volume into equation 1:

Since the given in the problem both have 3 significant figures, the final answer must also have three significant digits only. Therefore,

The density of glycerol is greater than 1, so when mixed with water it will sink.
