How many grams of caffeine will dissolve in 100 grams of water at 100 degrees Celsius?

Answer 1

67.0 grams of caffeine will dissolve in 100 mL of water at 100 degrees Celsius.

100mL of water = 100g of water

so..

67.0 grams of water will dissolve in 100 grams of water at 100 degrees Celsius.

I pretty sure this is right, I was searching for the answer myself and it seems to work.

But more accurately you will need to find the density of water at 100 ºC which is 0.9584 g/mL. So, 100g/0.9584 g/mL equals about 104 mL. Then 104 mL x 67.0g/100 mL = 69.9 g.

Answer 2

According to the phase diagram of water/sugar system,

at 80 degrees celsius, 26 wt% water will disolve 74 wt% of sugar.

example, 1000 grams of water can disolve 2846.15 grams of sugar

Answer 3

its not only 100 degrees celsius, tab water can dissolve copper sulfate, any water can dissolve copper sulfate, 10 ml of water can dissolve about 2.03 ml of copper sulvate
