Question 1068690: you are asked to prepare 100 ml of a potassium permanganate solution so that a 1 part to 3 parts dilution gives a 0.5 % w/v solution. How much potassium permanganate should be used?
the answer that i found was 1.5g but in my textbook it says "2g"
i thought 1 part to 3 parts means 1 part of the active ingredient and 2 parts of the diluent/water am i wrong ?
another question the ratio 1:10 does it mean 1 part of the active ingredient and 9 parts of the diluent/water or 10 parts of the diluent/water Answer by josgarithmetic(39617) (Show Source):
1 part by volume of the concentrated solution will be added to 3 parts of water, being total of 4 parts. Consider using all 100 ml of the concentrated solution.
