Question

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.

Answer 1

To determine the volume of isopropyl alcohol required for the experiment, divide the mass by the density of the alcohol.

Step-by-step explanation:

To determine the volume of isopropyl alcohol required for the experiment, we can use the density of the alcohol. The formula for density is mass divided by volume. In this case, the density of isopropyl alcohol is 0.785g/mL. So, we can rearrange the formula to solve for volume: volume = mass/density. Since the experiment requires 45.6g of isopropyl alcohol, we can substitute the values into the formula to find the volume: volume = 45.6g / 0.785g/mL = 58.153 mL. Therefore, 58.153 mL of isopropyl alcohol is required for the experiment.

Answer 2

58.089 mL

Step-by-step 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 data:

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
