What Is The Molarity Of A Solution Containing 20 Grams Of Naoh In 500 Milliliters Of Solution

500 ml of a solution contains 20 grams of NaOH (mw = 40). Calculate the molarity of the solution. 20 gr of NaOH correspond to 0.5 moles which are contained in 0.5 liter of solution. In one liter of solution there will be (2)(0.5) = 1 mole and thus the solution is 1 M.

What is the molarity of a solution containing 10g of NaOH in 500 mL of solution?, 5 mol L−1.

Furthermore, How many grams of NaOH are there in 500 mL of a 0.225 M NaOH solution?, Therefore, mass of NaOH in 500 mL of 0.225 M NaOH solution is 4.5 g.

Finally,  What is the molarity of a solution that contains 8.4 g NaOH in 240.0 mL of solution?, What is the molarity of a solution that contains 8.4 g NaOH in 240.0 mL of solution. Show all work. All tutors are evaluated by Course Hero as an expert in their subject area. 8.4 g NaOH = mass / molar mass = 8.4 g / 40 g / mole = 0.21 mole.

Frequently Asked Question:

How do you find molarity from NaOH to mL?

The molarity of NaOH is 2.002 x 10 2 moles x 1000 mL/L / 25.0 mL = 0.801 Molar.

How do you calculate the molarity of NaOH?

The molarity of the NaOH solution is found by dividing the moles of NaOH by the liters of NaOH solution required to reach the endpoint of the titration.

What is the molarity of NaOH in 250mL solution?

Therefore 5g of NaOH is present in 250mL of 0.5M NaOH solution.

What is the molarity of a solution containing 20 grams of NaOH in 500 milliliters of solution?

Number of moles of NaOH = 20gm40gm/mol = 0.5 moles. Therefore, 20 gm NaOH dissolved in 500 ml of solution has 1M of molarity.

How many grams of NaOH are there in 500 ml of a 0.175 M NaOH solution?

1 Answer. Under 4.0⋅g of sodium hydroxide.

How many grams of NaOH are there in 500 ml of solution?

4. 500 ml of a solution contains 20 grams of NaOH (mw = 40).

How do you prepare 500.00 ml of a 0.1 m NaOH solution from NaOH s )?

The question asked: “What mass of solid NaOH is needed to make 500mL of 0.1M NaOH solution?” To make one mole NaOH solution, dissolve 40 grams NaOH in 500mL of H2O.

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

Explanation: 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 molarity of a solution prepared by dissolving 10.0 grams of NaOH?

What is the molarity of a solution prepared by dissolving 10.0 grams of NaOH in enough water to make a solution with a total volume of 2.40 liters? 0.104 M NaOH.

What is the molarity of a solution containing 20 g of NaOH in 500 mL of solution?

Number of moles of NaOH = 20gm40gm/mol = 0.5 moles. Therefore, 20 gm NaOH dissolved in 500 ml of solution has 1M of molarity.

What is the molarity of 10 NaOH?

of moles of solute / volume of solution. i.e 10/40 = 1/4 i.e 0.25M.

How do you make a 10% NaOH solution?

Requirements

  1. Step 1: To prepare 100 ml of 10 M NaOH solution, weigh out 40 g of NaOH (molecular weight 40).
  2. Step 2: Dissolve NaOH pellet in 70 ml water by adding small quantities of NaOH in the water at a time. …
  3. Step 3: Adjust the solution volume to 100 ml with deionized/double distilled water. …
  4. 50 ml.
  5. 100 ml.
  6. 250 ml.
  7. 500 ml.

What is the normality of 10% NaOH solution?

Normality and molarity of sodium hydroxide are the same. The normality of 10% is 2.5 so, in theory at least, diluting it 25 times should render a normality of 0.1N.
