Answer:
25%
Explanation:
Given:
Volume of solute = 25 mL
Volume of solution = 100 mL
Required: Percentage by Volume
(Note: If given is "ml" it is volume. And if the given is "g", it is mass.)
Formula: % by mass = Volume of Solute / Volume of Solution x 100
Solution:
% by mass = 25 / 100 X 100
= 0.25 X 100
= 25%
Therefore the percentage volume by volume is 25%.
