Answer:
1188 grams
Explanation:
You want the 12g of sugar to be 1% of the whole solution.
So, say you add grams of water. The solution will be composed of 12 grams of sugar and grams of water, for a total of grams.
So, the ratio "sugar/total" will be
and we want this ratio to be 1%, i.e. 1/100:
Multiply both sides by 100 and to get
Subtract 12 from both sides:
So, a solution composed of 1188 grams of water and 12 grams of sugar will be 99% water and 1% sugar.
