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 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.
Which solution is more concentrated?
1 molar aqueous solution is more concentrated than 1 molal aqueous solution because 1 molar solution contain 1 mole of solute in 1 litre of the solution which include both solute and solvent. So, the mass of solvent (i.e. water) is less than 1000 gram.
What will molarity of 10 NaOH WV solution?
of moles of solute / volume of solution. i.e 10/40 = 1/4 i.e 0.25M.
How many grams of NaOH are in 500ml of a 1m solution?
4 gramsNaOH has the molar mass of 40g/mol. Therefore Mix 4 grams of NaOH in 500ml of water and your 0.1 M NaOH solution is ready.
How do you make 1m NaOH?
If you need to prepare roughly one liter of 1 M NaOH solution, you dissolve the molar mass of NaOH (40.0 g) using distilled water in a beaker, then transfer this solution to a one liter volumetric flask and rinse the beaker with distilled water several times and put it in the volumetric flask, and finally fill the …
