When 4 g of NaOH is dissolved in a 250mL of solution then find molarity of the solution?

=0.4mol L-1=0.4M.

How do you calculate the standardization of NaOH?

To Standardize:

1. Transfer 25.00 mL (measured with a calibrated pipette) into a 250 mL Erlenmeyer flask and dilute with an equal volume of water.
2. Add 1 M NaOH to raise the pH to 12 (measure with a pH meter or pH paper).
3. Add 4-8 drops of hydroxynaphthol blue indicator to the solution and record the color.

How do you find the concentration of HCl from titration with NaOH?

1. Volume of sodium hydroxide solution = 25.00 ÷ 1000 = 0.0250 dm 3
2. Amount of sodium hydroxide = 0.200 × 0.0250 = 0.005 mol.
3. From the equation, 0.005 mol of NaOH reacts with 0.005 mol of HCl.
4. Volume of hydrochloric acid = 22.70 ÷ 1000 = 0.0227 dm 3
5. Concentration of hydrochloric acid = 0.005 mol ÷ 0.0227.
6. = 0.220 mol/dm 3

What is the molarity of a solution containing 4g of NaOH in 1000 mL solution?

Thus, molarity of the solution is 0.1 M .

What is the molarity of Nios solution if 250 ml of it contains 1 mg of animals?

Molarity=10−340×1000250=10−4 M.

What is the molarity of NaOH dissolved in 250mL of h20?

The molarity of a solution containing 1.0 g NaOH in 250 mL of water is: 0.5 M.

What is an equivalence point titration?

Equivalence point: point in titration at which the amount of titrant added is just enough to completely neutralize the analyte solution. At the equivalence point in an acid-base titration, moles of base = moles of acid and the solution only contains salt and water.

What is the molarity of 4g of NaOH?

From the above calculation, it is clear that the molarity of the solution is 1M.

What is the molarity of NaOH in solution prepared?

To calculate the number of moles one must know the molecular mass of the substance. The molecular weight of sodium hydroxide is $40g/mol$. The molarity of sodium hydroxide in the solution prepared by dissolving its \[4g\] in water to make a solution of \[250mL\] is $0.4M$.
