Question

A solute with a density of 1.15 g/mL and mass of 45.95 g is dissolved in 250. mL of water. What is the volume of the solute, and what is the volume percent (v/v)?

Answer 1

39.95 mL is the volume of the solute

13.77% is the volume percent (v/v).

Step-by-step explanation:

Density of solute = 1.15 g/mL

Mass of solute = 45.95 g

Volume of the solute = V

`Density=(Mass)/(Volume)`

`V=(45.95 g)/(1.15 g/mL)=39.95 mL`

Volume of the solvent that water = 250 mL

Volume of the solution = 250 mL + 39.95 mL = 289.95 mL

Volume percent (v/v):

`\frac{\text{Volume of solute}}{\text{Volume of the solution}}* 100`

`(v/v)\%=(39.95 mL)/(289.95 mL)* 100=13.77\%`

39.95 mL is the volume of the solute

13.77% is the volume percent (v/v).
