The molar mass of NaNO3 is 85.0 g/mol. Therefore, 1 mole of NaNO3 is equal to 85.0 grams.
Approximately 34 grams of KCl will dissolve in 100 grams of water at 10 degrees Celsius. This is the solubility limit of KCl at that temperature.
The amount of solute that will dissolve in water at a specific temperature depends on the solubility of the solute at that temperature. You need to check the solubility of the specific solute at the specified temperature (in degrees Celsius) to determine how many grams will dissolve in 100 grams of water.
Approximately 27.5 grams of KCl will dissolve in 100 g of water at 50 degrees Celsius.
For this you need the atomic (molecular) mass of NaNO3. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. NaNO3=85.0 grams60.1 grams NaNO3 / (85.0 grams) = .707 moles NaNO3
To calculate the amount of NaNO3 needed to form a saturated solution at 45°C, the solubility of NaNO3 at this temperature must be known. Once this value is determined, the grams of NaNO3 required can be calculated using the solubility value and the saturation point equation.
Approximately 180g of sodium nitrate will dissolve in 50g of water at 60°C.
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.
When the temperature is lowered from 50°C to 20°C, the solubility of NaNO3 in water decreases. This causes excess NaNO3 to precipitate out of the solution. The amount that precipitates depends on the initial concentration and the solubility curve of NaNO3. The exact calculation would involve using the solubility data for NaNO3 at different temperatures.
Approximately 31 grams of KNO3 will dissolve in 100 g of water at 30 degrees Celsius. This value may change slightly based on the specific conditions, such as impurities in the water or agitation of the solution.
Approximately 42 grams of KCl can dissolve in 100 grams of water at 80°C.
The solubility of poassium nitrate in water at 20 oC is 616 g/L.
