How many grams of NaOH should be added to 250 ml?

20 gAnswer. 20 g of NaOH should be added to water to prepare 250 ml solution of 2 M NaOH. Solution: Molarity is defined as the amount of moles of a compound dissolved in an amount of solvent.

What is Molality formula?

molality = moles of solute / mas of solvent (kg) molality = 0.0117 mol / 0.341 kg molality = 0.034 mol/kg. Answer : The molality of the sugar solution is 0.034 mol/kg.

How do you make a 10% NaOH solution?

The preparation of 10 N NaOH involves a highly exothermic reaction, which can cause breakage of glass containers. Prepare this solution with extreme care in plastic beakers. To 800 mL of H2O, slowly add 400 g of NaOH pellets, stirring continuously. As an added precaution, place the beaker on ice.

How many grams of NaOH are in 250 ml of a 3.0 m Naoh solution?

It’s a 3.0 M solution so 1 litre of solution contains 3 moles of NaOH. 250 ml of solution therefore contains 0.25 x 3 = 0.75 moles of NaOH. The molar mass of NaOH is 39.9971 g/mol, so 250 ml of this solution contains 0.75 x 39.9971 = 29.99 g, or if you round it up 30.0 g.

What is the mass of NaOH in 250ml of 10% solution?

Answer: The number of grams of NaOH to be added to water to prepare 250ml solution of 2M NaOH is 20 grams. Explanation: Molarity is defined as the ratio of the amount of solute to the solution or the amount of moles dissolved the amount of solvent in the total moles of total solution.

How do you make 500mL of 2m NaOH?

Explanation: To make 500 mL of 2.00 M NaOH solution, you need to make sure that every litre of the solution contains 2.00 mol of NaOH . So, 1 L of 2.00 M NaOH solution contains 2.00×(23.0 + 16.0 + 1.0) g NaOH . And 500 mL of 2M NaOH solution contains 80.02g NaOH=40.0 g of NaOH .

How do you make 40% NaOH?
