How do you find the molarity of 85% phosphoric acid?

How do you find the molarity of 85% phosphoric acid?

We simply need the solution density and solute molecular mass (97.994 g·mol−1) to readily calculate the molarity of the commercial 85 [wt]% phosphoric acid. The corresponding density is 1.685 g/cm3 at 25 °C (*). The molarity is: 0.85(g H3PO4 / g aq.

What is the concentration of 85% phosphoric acid?

Therefore, we can say that 1 liter of Phosphoric acid contains 14.615 moles or in other words molarity of 85% (w/w) Phosphoric acid is equal to 14.615 M….Known values.

What is the molarity of phosphoric acid in a solution Labelled 20.0% phosphoric acid H3PO4 by weight with a density 1.12 g mL?

=11.85 mol/L.

How do you make 10 phosphoric acid?

  1. In 100 gram diluted solution you have 1.25 g phosphoric acid.
  2. In the 10% solution we have for every gram phosphoric acid 10 gram 10% solution.
  3. To end with 1.25 g acid you need 10 x 1.25 = 12.5 g of the 10% solution.
  4. This 12.5 gram must be present in 100 gram diluted solution, so you must add 100 – 12.5 = 82.5 gram water.
