How on earth do you find the molarity of a 750 ml solution containing 346g of potassium nitrate?
To find the molarity of the solution, you need to first calculate the number of moles of potassium nitrate present in 346g. Then, use the formula:
Molarity (M) = moles of solute / volume of solution in liters
Convert 750 ml to liters and divide the moles of potassium nitrate by the volume to find the molarity.

What bond is break in order to form potassium nitrate solution?
In order to form a potassium nitrate solution, the ionic bond between potassium ions and nitrate ions in the solid potassium nitrate compound needs to be broken. This allows the potassium and nitrate ions to separate and become surrounded by water molecules, resulting in the formation of a potassium nitrate solution.
What is the conductivity of potassium nitrate?
The conductivity of potassium nitrate depends on its concentration in solution. Generally, potassium nitrate is a strong electrolyte, meaning it dissociates completely into ions in solution and conducts electricity well.
How do you separate potassium nitrate and water using separating techniques?
One common method to separate potassium nitrate and water is by using the process of evaporation. The solution containing both substances is heated until the water evaporates, leaving behind solid potassium nitrate. Another method is through filtration, where the solution is passed through a filter paper to separate the solid potassium nitrate from the liquid water.
What causes the equilibrium to shift when a cooled saturated potassium nitrate solution is added to water?
When a cooled saturated potassium nitrate solution is added to water, the solubility of potassium nitrate decreases due to the decrease in temperature. This causes the equilibrium to shift to the left, leading to the precipitation of excess potassium nitrate as solid crystals.
How we obtain pure potassium nitrate which is free of soil?
Pure potassium nitrate can be obtained by dissolving a source of potassium nitrate, such as KNO3 crystals, in water and then filtering the solution to remove any soil or impurities. The filtered solution can then be evaporated to dryness, leaving behind pure potassium nitrate crystals.
What is the molarity of 20.2 g of potassium nitrate in enough water to make 250.0 mL of solution?
To find the molarity, first calculate the number of moles of potassium nitrate using its molar mass (101.1 g/mol). This comes out to 0.2 moles. Then, divide the moles by the volume of the solution in liters (0.250 L) to get the molarity, which is 0.8 M.
What is the molarity of a solution that contains 4.53 moles of lithium nitrate in 2.85 liters of solution?
This molarity is 1,59.
Is potassium nitrate more dense than water?
It depends on the Molarity of the solution. if the (mols x molar mass)/volume> 1, its more dense.

What is aqueous potassium nitrate?
Aqueous potassium nitrate is a solution of potassium nitrate (KNO3) dissolved in water. It is a colorless, odorless liquid and is commonly used in fertilizers, food preservation, and as a source of nitrate ions in chemical reactions.
What causes the equilibrium to shift when a cooled saturated potassium nitrate solution is added to water?
When a cooled saturated potassium nitrate solution is added to water, the solubility of potassium nitrate decreases due to the decrease in temperature. This causes the equilibrium to shift to the left, leading to the precipitation of excess potassium nitrate as solid crystals.
What ions are left in solution after reacting 250.0 ml of a 0.10M Barium Nitrate solution with 200 ml of a .10 potassium phosphate solution?
The reaction between barium nitrate (Ba(NO3)2) and potassium phosphate (K3PO4) will form barium phosphate (Ba3(PO4)2) and potassium nitrate (KNO3). The ions left in solution will be potassium (K+) and nitrate (NO3-) ions from the potassium nitrate. The barium phosphate will precipitate out of solution.
What is the solute and solvent of potassium nitrate solution?
In a potassium nitrate solution, potassium nitrate is the solute and water is the solvent. Potassium nitrate dissolves in water to form a homogeneous solution.
A saturated solution potassium nitrate may be made unsaturated by?
Increasing the temperature of the solution, which will allow more potassium nitrate to dissolve. Alternatively, adding more solvent to the solution can also make it unsaturated by diluting the concentration of potassium nitrate.

Pure potassium nitrate can be obtained by dissolving a source of potassium nitrate, such as KNO3 crystals, in water and then filtering the solution to remove any soil or impurities. The filtered solution can then be evaporated to dryness, leaving behind pure potassium nitrate crystals.
