Molarity of 37% HCl Solution
Hydrochloric Acid is nothing but the hydrogen chloride gas aqueous solution. The molar mass of hydrochloric acid is 36.6 g/mol and the density of 37% hydrochloric acid is 1.2 g/ml.
Calculate the weight of hydrochloric acid for 1000 ml, using the mentioned formula.
Weight = volume x density
Weight = 1000 x 1.2 = 1200 g
So, the weight of 1000 ml of hydrochloric acid is 1200g.
Calculating the amount of hydrogen chloride in the 1200g based on this information.
100 g of hydrochloric acid contains 37 g of hydrogen chloride.
So, 1 g of hydrochloric acid have 0.37 g (37/100) of hydrogen chloride.
1200 g hydrochloric acid having 1200 x 0.37 = 444 g of hydrogen chloride.
According to the calculations described above, the 1000 ml of hydrochloric acid solution contains 444 g of hydrogen chloride.
Then the molarity of 37% HCl is,
No. of Moles = Weight/molar mass
No. of moles = 444 / 36.6 = 12.1311 moles.
