Question

Calculate the volume of ethanol in 200 ml solution of 20%

Answer 1

Answer:

Since you are given v/v % and you have to calculate volume only. So, just find out the percentage of ethanol in 200 ml of solution.

i.e., 20/100×200 = 40 ml.

Therefore 40ml of ethanol(C2H5OH) is present in that solution.
