What is the volume of 35.0 g of propylene glycol if the density of propylene glycol is 1.036 g/ cm3?

a.33.8 cm3

b.33.78 cm3

c.34 cm3

d.33.784 cm3

Answer : The volume of propylene glycol is, (A)

Explanation : Given,

Mass of propylene glycol = 35.0 g

Density of propylene glycol =

Density : It is defined as the mass of a substance present in unit volume of solution.

Formula used :

Now put all the given values in this formula, we get the volume of propylene glycol.

According to the significant rule of division and multiplication the least number of significant figures in any number of the problem determines the number of significant figures in the answer.

The least precise number of significant number in the problem is, 3. So, the answer should be in 3 significant figures.

Hence, the volume of propylene glycol is,
