Question

If 14.7 cm3 of alcohol is present in 70 cm 3 of its aqueous solution, the percentage by volume of alcohol will be?

Answer 1

Answer: The percentage by volume of alcohol will be 21%.

Step-by-step explanation:

Given: Volume of solute = 14.7
`cm^(3)`

Volume of solvent = 70
`cm^(3)`

Formula used to calculate percentage by volume is as follows.

`Percentage volume = (volume of solute)/(volume of solvent) * 100`

Substitute the values into above formula as follows.

`Percentage volume = (volume of solute)/(volume of solvent) * 100\\= (14.7 cm^(3))/(70 cm^(3)) * 100\\= 21 percent`

Thus, we can conclude that the percentage by volume of alcohol will be 21%.
