Using your Periodic Table, look up the Atomic Mass of each element. Add up potassium, nitrogen and 3 x oxygen. This is the grams per mole of potassium nitrate. I am sure you learned the rest. You will be multiplying this molar value by 0.03 Use the balance to weigh out this amount.
To prepare 0.03 M KNO3 solution, you would dissolve the appropriate amount of KNO3 in a given volume of water. The formula to calculate the mass of KNO3 needed is: mass (g) = molarity (M) x volume (L) x molar mass (g/mol). Once you have calculated the mass needed, dissolve it in water to make the final volume.
1. Weigh 2,528 g ultrapure dry KNO3.
2. Transfer KNO3 in a clean 100 mL volumetric flask using a funnel. 3. Wash the funnel with 80 mL demineralized water.
4. Put the flask in a thermostat and maintain 30 min at 20 0C.
5. Add demineralized water up to the mark.
6. Stir vigorously and transfer in a clean bottle with stopper.
7. Add a label with necessary information.
The molarity of the KNO3 solution is 0.544 M. This is calculated by dividing the moles of KNO3 (1.1 mol) by the total solution volume in liters.
The chemical formula KNO3 is for potassium nitrate.
What is the specific heat capacity of kno3
You can separate KNO3 from its aqueous solution by a process called evaporation. Simply heat the solution to evaporate the water, leaving behind solid KNO3. This method exploits the fact that KNO3 has a much higher boiling point compared to water.
Ammonia can be mixed with KNO3 at room temperature.
To prepare 250 ml of 0.150 M KNO3 solution, you would need to dilute the stock solution (2.00 M KNO3) with a certain volume of water. You can use the formula for dilution: M1V1 = M2V2, where M1 is the initial concentration (2.00 M), V1 is the initial volume (unknown), M2 is the final concentration (0.150 M), and V2 is the final volume (250 ml). Rearrange the formula to solve for V1: V1 = (M2 * V2) / M1. Substitute the values: V1 = (0.150 M * 250 ml) / 2.00 M = 18.75 ml. You would need 18.75 ml of the stock solution to prepare 250 ml of 0.150 M KNO3 solution.
To calculate the grams of KNO3 needed, first, find the molar mass of KNO3 (101.1 g/mol). Then, use the formula: mass = molarity x volume x molar mass. Plugging in the values gives mass = 0.50 mol/L x 2.0 L x 101.1 g/mol = 101.1 grams of KNO3.
The molarity of the KNO3 solution is 0.544 M. This is calculated by dividing the moles of KNO3 (1.1 mol) by the total solution volume in liters.
To find the total moles of KNO3 needed, use the formula: moles = molarity x volume (in liters). So, moles = 2.0 mol/L x 1.5 L = 3.0 moles of KNO3. Therefore, 3.0 moles of KNO3 need to be dissolved in water to make 1.5 liters of a 2.0 M solution.
