What is the formula for potassium nitrate dissolved in water?
KNO3(s) -----> K+(aq) + NO3-(aq)
How much potassium nitrate will dissolve in 50 grams of water at 50C?
65 degrees of potassium nitrate will remain in water while only 35% of water will still be detectable in the solute potassium nitrate
A KNO3 solution containing 45 g of KNO3 per 100g of water is cooled from 40 degrees celciuswhat will happen during cooling?
As the solution is cooled, the solubility of the solution decreases and a precipitate will form.
In which is KNO3 soluble benzene hexane or water?
Potassium nitrate is soluble in water, as it is an ionic solid. When dissolved in water, potassium nitrate will form an aqueous solution of potassium and nitrate ions.
How many number of elements does KNO3 have?
KNO3 has 3 elements which are potassium, Nitrogen and Oxygen.
How many grams of KNO3 will dissolve in 100 g of water at 30 degrees Celsius?
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 :)
KNO3 at 60 degrees Celsius?
Potassium nitrate is a solid at 60 oC.
How may grams of KNO3 should be used to prepare a 2.0L of a 0.50 M solution?
Get moles by; Molarity = moles of solute/Liters of solution 0.50 M KNO3 = moles KNO3/2.0 L = 1.0 mole KNO3 Now find grams of 1.0 mole KNO3 1.0 mole KNO3 (101.11 grams/1 mole KNO3) = 101.11 grams KNO3 needed call it 100 grams
Why cannot 100ml of KNO3 solution hold more than 37gm of KNO3 in a dissolved state?
Why 100 ml solution of KOH3 can not hold more than 37gm of KNO3 in dissolved state
Why 100ml solution of KNO3 can not hold more than 37 gm of KNO3 in dissolved state?
potassium nitrate solubility at room temperature 25 degree celsius is about 383 g /L.if we want per 100 ml then .... 383 g / 1000ml ....we know that1 L=1000mlnow for per 100 ml it becomes38.3g/100mlnow we can see that KNO3 solubility in 100 ml solution is 38.3 g.....so we can say that100 ml solution of KNO3 can not hold more than 37 g or 38.3 g of KNO3 in dissolved state.
The vapour pressure of water at 25degrees is 3.14kPa When 0.050 mol of KNO3 is dissolved in 100ml of water at 25 degrees the vapour pressure is lowered by?
Read a text book
How many molecules would be found in 427.4 grams of potassium nitrate?
Quite a few! 427.4 grams KNO3 (1 mole KNO3/101.11 grams)(6.022 X 1023/1 mole KNO3) = 2.546 X 1024 molecules of potassium nitrate -----------------------------------------------------------
How many moles of KNO3 are in 6.5 grams?
The molecular weight of potassium nitrate (KNO3) is 101.1 grams/mole.K = 39.1 + N = 14.0 + O = 3*16.0 = 101.1Now divide 6.5 by 101.1 to calculate # of moles => 0.064 moles KNO3
Why test tube becomes cold when KNO3 is dissolved in water?
The dissolution is an endothermic process.
What is the formula for potassium nitrate dissolved in water?
KNO3(s) -----> K+(aq) + NO3-(aq)
What is the molecular formula for potassium nitrate?
The chemical symbol for potassium nitrate is potassium. "KNO3"
How many total moles of KNO3 must be dissolved in water to make 1.5 liters of a 2.0 M current?
8 moles of KCl are needed.
