When 20.0 grams of NaOH is dissolved in 500 mL of solution the concentration of the solution is?

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 a solution containing 20 grams of NaOH?

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 the solution which contains 5.0 g of NaOH dissolved in water to make 200 mL of solution?

Molarity of NaOH solution is 0.625 M.

What is the concentration in mol dm 3 of 20.0 g of NaOH in 500.0 cm 3?

So the amount of NaOH in 20.0 cm 3 is 0.025 mol.

When 2 g of NaOH is dissolved in 500 cm³ of water then molarity of NaOH will be?

Molarity = 0.10⋅mol⋅L−1 with respect to NaOH .

What will be the concentration when 20 g of NaOH is present in 200 ml of solution?

20g*1 mole NaOH/40.0g=0.5 mol NaOH. =2.5 M. Thus, the molarity of a solution that contains 20.0 grams of sodium hydroxide in a 200ml solution is 2.5 M.

What is the molarity of a solution of NaOH?

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

What is the molarity of 5\% NaOH?

Concentration lectures What is molar concentration of 5\% solution of sodium hydroxide? However, wee need two additional informations: molar mass and density of the solution. Molar mass of NaOH is 40.00, in density tables you can find value of 5\% NaOH solution density – 1.0554 g/mL. 10×5×1.0554/40.00=1.32 M.

What is the molarity of a solution containing 5 g of NaOH in 50 mL solution?

Hope it helps. No. of moles of solute= Mass of solute /molar mass. So, Moles of solute =0.5/40 =0.0125.

What is the molarity of a solution containing 10g of NaOH in 500ml of solution?

5 mol L−1.

How do you find the concentration in g dm 3?

Rearranging the equation for concentration allows the mass of solute to be calculated:

  1. mass of solute in g = concentration in g/dm 3 × volume in dm 3
  2. A solution of sodium chloride has a concentration of 10 g/dm 3.
  3. mass of solute in g = concentration in g/dm 3 × volume in dm 3
  4. = 10 g/dm 3 × 2 dm 3

What is the resulting molarity of solution when 2g of NaOH is dissolved in 500 ml of water?

How do you calculate liters of solution from 1 mol of NaOH?

Solution: 1 mol of NaOH has a mass of 40.00 g, so. #”Moles of NaOH” = 15.0 cancel(“g NaOH”) × “1 mol NaOH”/(40.00 cancel(“g NaOH”)) = “0.375 mol NaOH”#. #”Litres of solution” = 225 cancel(“mL soln”) × “1 L soln”/(1000 cancel(“mL soln”)) = “0.225 L soln”#.

What is the mass of the solute in NaOH?

To obtain the mass of solute, we will need to the molar mass of NaOH, which is 40.00 g/mol: Finally, multiply the number of moles by 40.00 g/mol

How to find the molarity of a sodium hydroxide solution?

>> The molarity of a sodium hydroxide solution can be determined by dividing the amount of sodium hydroxide (in moles) present by the number of liters of the overall solution. >>For example, if there are 50 moles of NaOH in 500 liters of solution, it is a 0.1 molar NaOH solution.

How to prepare 500 ml of 2n NaOH solution?

To prepare 500 ml.of 2N NaOH we require =40 x 500 x 2/1000 =40 gm. So to prepare 500 ml.of 2N NaOH we require 40 gm. of NaOH. The solution of NAOH contains 30 gms of this compound in 1.5 dm3 of solution.
