To determine the number of grams of water needed to dissolve 612 grams of sugar at 20°C, we can use the information about the solubility of sugar given in the question.
The solubility is stated as 204 g of sugar in 100 g of water. This means that 204 grams of sugar can dissolve in 100 grams of water at 20°C.
We can set up a proportion to solve this problem:
204 g sugar / 100 g water = 612 g sugar / x g water
To find x, we cross-multiply:
204 g sugar * x g water = 612 g sugar * 100 g water
Now we can solve for x:
x g water = (612 g sugar * 100 g water) / 204 g sugar
x g water = 300 g water
So, 300 grams of water are needed to dissolve 612 grams of sugar at 20°C.
204 grams of sugar dissolve in 100 g of water.
=> 1 gram of sugar dissolves in (100/204)g of water
=> 612 grams of sugar dissolves in 612*(100/204)g of water
