## How do you calculate the molarity of HCl stock solution?

Molarity is a ratio between moles of solute and volume of solution. By dividing the number of moles of HCl by the volume (L) of solution in which it was dissolved, we will obtain the molarity of the acid solution.

What is the molarity of stock HCl?

Dilutions to Make a 1 Molar Solution

Concentrated Reagent Formula Weight1 Molarity (M)
Hydrochloric Acid (HCl) 36.461 12.1
Hydrofluoric Acid (HF) 20.006 28.9
Nitric Acid (HNO3) 63.013 15.6
Perchloric Acid (HClO4) 100.46 11.7

What is the stock solution of HCl?

29.2% (w/w) HCl stock solution has a density of 1.25 gml−1.

### How will you prepare 0.1 M HCl from stock solution?

Preparation and Standardization of 0.1 M Hydrochloric acid (HCl)

1. Take about 100 ml of water in a cleaned and dried 1000 ml volumetric flask.
3. Add more about 700 ml of water, mix and allow to cool to room temperature.
4. Make up the volume 1000 ml with water.

How do you find the molarity of 36% HCl?

The molarity is: 0.37(g HCl / g aq. sol.) 1.184(g aq. sol. / cm3)·(1000 cm3/dm3)/(36.46 g HCl/mol HCl) = 12.02 M (approximate).

What is 37 HCl molarity?

Therefore, we can say that 1 liter of Hydrochloric acid contains 12.178 moles of HCl or in other words molarity of 37% (w/w) Hydrochloric acid is equal to 12.178 M.

## How do you find the molarity of a stock solution?

The molarity (M) of a solution is the number of moles of solute dissolved in one liter of solution. To calculate the molarity of a solution, you divide the moles of solute by the volume of the solution expressed in liters.

How do you find the molarity of 37 HCl?

1. 37% HCl means, 37- g of HCl is present in 100- ml of the solution.
2. So 1000- ml of the solution will contain = 370- g of HCl.
3. So Molarity of 37% HCl SOLUTION= 370/36.5 = 10.14 M.
4. So 50 x 1 = 10.14 x V.
5. So V= 50 x 1/10.14= 4.93- ml.

What is the molarity of 37 HCl?

### What is the molarity of 38% HCl?

12.61 Molar
Molarity = 12.61 Molar and 7.96 ml of HCl(38%) needed for 1.0 Liter of 0.10 Molar HCl(aq).

What is the molarity of 10 HCl?

solution of concentrated HCl using measuring cylinder & add enough water to make final volume 500 mL in a suitable container. since it is 10 times diluted, normality/ Molarity will be approximately 1.2 N/M.
