What percent is 2 normal hydrochloric acid?

Answer 1

Answer 2N HCl would be 2 moles/dm3. Weight of 1 mole of HCl = 36.5 g

Weight of 2 moles of HCl = 73 g 1 dm3 of water = 1 litre of water.

1 litre of water weighs 1 kg = 1000 g Weight % = (73/1000) x 100 = 7.3 % Answer The term normal is not really used any more. I believe it was replaced by the word molar, which again has been replaced by the units of 'moles per decimetre cubed' mol/dm3. So 2 mol/dm3 hydrochloric acid would contain 2 moles of HCl in each litre of water. 2 moles of HCl is 73 grams (twice the formula mass). But since you purchase HCl as a liquid, you don't make up the concentration you want by weighing it out, like you would do a solid. You make it up by diluting the stock that you bought.

Answer 2

About 0.5% (5000 parts per million) of stomach acid is hydrochloric acid.

Answer 3

The percentage is 1,7 % for the dissolved hydrogen chloride (HCl).

Answer 4

2 normal hydrochloric acid is equivalent to 20% hydrochloric acid.
