An experiment requires 45.6g of isopropyl alcohol as reagent. Instead of measuring the mass of a liquid on a balance you decide to determine the mass by using an equivalent volume measured in a graduated cylinder. The density of isopropyl alcohol is 0.785g/mL. What volume of the alcohol is required for the experiment.

58.089 mL

Explanation:

Density:

Density is equal to the mass of substance divided by its volume.

Units:

SI unit of density is Kg/m3.

Other units are given below,

g/cm3, g/mL, kg/L

Formula:

D=m/v

D = density

m=mass

V=volume

Symbol:

The symbol used for density is called rho. It is represented by ρ. However letter D can also be used to represent the density.

Given dа ta:

density of isopropyl alcohol = 0.785 g/mL

mass = 45.6 g

volume = ?

Now we will put the values in the formula,

d = m/v

v=m/d

v = 45.6 g / 0.785 g/mL

v = 58.089 mL
