100 g water dissolve 45,8 g potassium chloride at 50 o 0C.
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.

Instead of waiting for the answer, I ended up solving it. lol 300grams of H20 X 110grams of KNO3/100 grams of H20 = 330 grams of KNO3 The grams of H20 both cancel out and leave you with 330 grams of KNO3 Containing the solubility of KNO3. At 60 degrees celsius the KNO3 grams were 110, which is (over) / 100grams of H20. Hope this helps with this workbook problem :)
No, but interestingly spearmint does at a temperature of 73.48 degrees celsius, 164.264 degrees fahrenheit.
yes
Aproximately 4 grams of potassium chlorate will dissolve in 50 g of water at 20 degrees celsius.

The answer is 134,645 grams of NaCl.

The solubility of poassium nitrate in water at 20 oC is 616 g/L.

The temperature would be that of water's boilng point od 100 degrees

No, sugar has a melting point of 161 degrees Celsius and salt has a melting point of 801 degrees Celsius
What is the density of water at 37 degrees Celsius?
Density of ice at 0 degrees Celsius is 916.8 grams per cubic centimeter or milliliter. The density of fresh water is dependant on the temperature: At 3.98 degrees Celsius the density is 0.999975 grams per milliliter. At 100 degrees Celsius the density is 0.958.35 grams per milliliter.
