Answer:
You can add 45 grams of water to 15 grams of sugar to make a 25% sugar solution.
Explanation:
To make a 25% sugar solution, you need to add a certain amount of water to 15 grams of sugar. To determine this amount, you can use the following formula:
(desired concentration / 100) x total volume = amount of solute (in this case sugar)
We know that the desired concentration is 25%, and the amount of solute is 15 grams. To find the total volume, we can use the following formula:
amount of solute / desired concentration = total volume
15 grams / 0.25 = 60 grams
So the total volume of the solution is 60 grams, and the amount of water you need to add to make a 25% sugar solution using 15 grams of sugar is 45 grams.
You can add 45 grams of water to 15 grams of sugar to make a 25% sugar solution.
Another way to think of it is to add 3 times the amount of water as the amount of sugar, since 25% of 60g is 15g
