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
Correct Answer: B (187.5 ml)
Explanation:
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.
