What is the molarity of a 2 g NaOH in 100 ml water?

Detailed Solution 2 grams of NaOH are needed to make 100 ml. of a 0.5 M solution of NaOH. So, mass of NaOH = 0.05*40 = 2 grams.

What will be the molarity of a solution which contains 2 g NaOH per 500 ml of the solution?

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

What is the molarity of a NaOH AQ solution containing 4 grams of NaOH in 100 ml of solution?

We assume that 4gm mass of NaOh is dissolved in 100ml volume of water and such a dissolution would involve minimal change to the volume of solution. Then Molarity=mole of solute/volume of solution in litre. , Molarity=4×1000/40×100 =1mole/litre. (mole=mass of solute/molecular mass of solute).

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 for 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 4 NaOH solution?

M=4×1040=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 $0.4M$.

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 a solution containing 10g of NaOH?

What is molarity of a solution containing 10 g of NaOH in 500 mL of NaOH solution? Molar mass NaOH = 40 g/mol#

How do you find the number of moles of NaOH?

We are given the mass of NaOH, not the number of moles. In order to find the number of moles of NaOH, you would divide the given mass by the molecular weight of NaOH, which is 39.997 g/mol.

What is the molarity of a mole?

Molarity is a concentration term in which the no. of moles and the volume are related. V = 500 mL = 0.5 L

What is the normality of 76\% (W/V) NaOH?

We know that 76.45\% (w/v) NaOH means 76.45 grams of NaOH in 100 mL solution. By using the following this formula. We can get normality of 76.45\% (w/v) NaOH. Step 3. By using dilution formula.
