If a chemical solution contains 8% of base, and there is 15ml of base, what is the volume of the solution?
A. 135.5 ml
B. 187.5 ml
C. 175.5 ml
D. 220.5 ml
To solve this problem, we can use the formula for percent by volume:
Percent by volume = (volume of solute / volume of solution) x 100%
Given that the solution contains 8% of the base and the volume of the base is 15 ml, we can find the volume of the solution by rearranging the formula:
Volume of solution = (volume of solute / percent by volume) x 100%
Plugging in the values, we get:
Volume of solution = (15 ml / 8%) x 100%
Calculating this, we find:
Volume of solution = 187.5 ml
Therefore, the correct answer is (B) 187.5 ml.
