Question 984097
I agree, it is 1/14

If there are 84 grams with a 1:14 solution, it should be 2% of the whole amount, which is diluted to 4.2 liters, or 50 fold.  

84 grams is 28% of a solution of 300 cc.
3.9 liters of water were added.
The first batch was 2100, to make it 1:8
The second batch was 1800, to reach 4200 cc or 4.2 liters.
