I believe it is 174.2592, but I could be mistaken. I believe it is 174.2592, but I could be mistaken. KNO3 has a molar mass of 101.10303
No, 120 g of potassium nitrate will not completely dissolve in 100 g of water at 40 degrees Celsius. The solubility of potassium nitrate in water at 40 degrees Celsius is approximately 62 g/100 g water. This means that only up to 62 g of potassium nitrate can dissolve in 100 g of water at this temperature.
The solubility of potassium chloride in water is about 34 g/100 g at room temperature. Therefore, the maximum amount that can be dissolved in 100 g of water is 34 g.
50 g of potassium chloride are dissolved in 100 g water at cca. 80 oC.
The specified amounts of materials add to 814.78 grams total. Therefore, the percentage concentration by mass of potassium iodate is 100(3.05/814.78) or 0.374 percent, to the justified number of significant digits, and the percentage concentration by mass of potassium hydroxide is 100(6.23/814.78) or 0.765 percent, to the justified number of significant digits.
The solubility of potassium chloride in water at 80 oC is 51,3 g/100 g.The solubility of sodium chloride in water at 80 oC is 37,93 g/100 g.
To find the weight percent of potassium nitrate in the solution, first calculate the total mass of the solution, which is the sum of the mass of potassium nitrate and the mass of water: 30.0 g + 90.0 g = 120.0 g. Next, use the formula for weight percent: (mass of solute / total mass of solution) × 100%. Thus, the weight percent of potassium nitrate is (30.0 g / 120.0 g) × 100% = 25.0%.
The solubility of potassium nitrate at 15 0C is 47 g/100 g water.
To calculate the theoretical mass percentage of oxygen in potassium chlorate, you would use the formula weight of oxygen divided by the formula weight of the compound (potassium chlorate) multiplied by 100. The formula weight of oxygen is 16.00 g/mol and the formula weight of potassium chlorate (KClO3) is 122.55 g/mol. So, (16.00 g/mol / 122.55 g/mol) * 100 = 13.06%.
the solubility of potassium nitrate in 70 degreesCelsius water is about 134 g KNO3 per 100 g water
Potassium oxalate is soluble as are all potassium compounds.
Aproximately 4 grams of potassium chlorate will dissolve in 50 g of water at 20 degrees celsius.
