What is the molarity of 10 W v HNO3 solution?
With 10\% nitric acid, 0.1 x 1500 gm/L = 150 gm/L. We know Molar mass of HNO3 = 63.01 g/mol.
What is the molar mass of HNO3?
63.01 g/mol
Nitric acid/Molar mass
What is the mole fraction of HNO3?
n is the number of moles. 1000 g solution = 1 kg. To calculate the molality, substitute the value of moles and mass of solution in kg in the above equation. Therefore, the mole fraction of $HN{O_3}$ is 0.0396 and the molality is 0.194 m.
How do you find the molarity of a dilute solution?
You can solve for the concentration or volume of the concentrated or dilute solution using the equation: M1V1 = M2V2, where M1 is the concentration in molarity (moles/Liters) of the concentrated solution, V2 is the volume of the concentrated solution, M2 is the concentration in molarity of the dilute solution (after …
How do you find the molarity of HNO3?
Dividing the grams of HNO 3 by the molecular weight of HNO 3 (63.01 g/mole) gives the number of moles of HNO 3 / L or Molarity, which is 15.7 M. Where: \% = Weight \%; d = Density (or specific gravity); MW = Molecular Weight (or Formula Weight).
How do you calculate molarity in chemistry?
Quick Review of Calculating Molarity. To calculate molarity: Find the number of moles of solute dissolved in solution, Find the volume of solution in liters, and. Divide moles solute by liters solution.
How do you find the molarity of KMnO4 solution?
Calculate the molarity of a solution prepared by dissolving 23.7 grams of KMnO 4 into enough water to make 750 mL of solution. This example has neither the moles nor liters needed to find molarity, so you must find the number of moles of the solute first.
What is the meaning of 10\% NaOH and molarity?
10\%NaOH means 100gm of solution present in 10gm of NaOH. Molarity is the no.of moles of solute present per litre of solution.
