Question

15 ml of alcohol is mixed with 60 ml of gasoline . calculate the volume by volume percentage of solution.

plz solve it with complete explination

Answer 1

Volume of solute = 15ml
Volume of solvent = 60ml
Volume of solution = Solvent + Solute
= 15 + 60= 75
concentration = (Volume of solute/Volume of solution)100
= (15/75)100
= 20%

Answer 2

Answer:

The volume-by-volume percentage of the solution measured is $20\%$

Explanation:

Given,

The volume of the alcohol (solute) = $15ml$

The volume of the gasoline (solvent) = $60ml$

The solution's volume-by-volume percentage =?

As we know,

• The volume-by-volume percentage of the solution can be calculated by the equation given below:
• V/V% = $\frac{volume of solute}{total volume of solution} \times 100$

Now,

• The total volume of the solution = volume of solute + volume of solvent
• The total volume of the solution = $15+60$ = $75ml$.

After putting the values in the equation, we get:

• V/V% = $\frac{15}{75}\times 100$ = $20\%$

Hence, the volume-by-volume percentage of the solution = $20\%$.
