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.

Explanation:

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

Mathematically,      Density = [tex]\frac{mass}{volume}[/tex]

It is given that volume is 3.25 L and mass is [tex]4.10 \times 10^{3} g[/tex]. Hence, calculate the density of glycerol as follows.

                     Density = [tex]\frac{mass}{volume}[/tex]

                                   = [tex]\frac{4.10 \times 10^{3} g}{3.25 L}[/tex]

                                    = [tex]1.26 \times 10^{3} g/L[/tex]

As, 1 L = 1000 [tex]cm^{3}[/tex].

So,           [tex]1.26 \times 10^{3} g/L \times \frac{1000 cm^{3}}{1 L}[/tex]

                 = [tex]1260 \times 10^{6} g/cm^{3}[/tex]    

Thus, we can conclude that the density of glycerol is [tex]1260 \times 10^{6} g/cm^{3}[/tex].
