What is the molarity of 85% phosphoric acid?
15.2 M .
The 85% phosphoric acid is equivalent to 15.2 M . In molarity the H3PO4 is a tribasic acid which means a normality of 45.6 N.
How do you make 1M 85 phosphoric acid?
So you need 0.0684 liters of 85% (w/w) concentrated Phosphoric acid solution to prepare a 1 liter of 1M Phosphoric acid solution.
What is the molarity of a solution of phosphoric acid?

How do you make 6 M phosphoric acid?
Adjust the recipes accordingly to make larger or smaller volumes. For example, to make 500 mL of 6M HCl, use 250 mL of concentrated acid and slowly dilute to 500 mL with water.
How do you calculate phosphoric acid?
H3PO4Phosphoric acid / Formula
How do you calculate molarity from normality?
If you know the Molarity of an acid or base solution, you can easily convert it to Normality by multiplying Molarity by the number of hydrogen (or hydroxide) ions in the acid (or base). For example, a 2 M H2SO4 solution will have a Normality of 4N (2 M x 2 hydrogen ions).
How many grams of pure phosphoric acid h3po4 is present in a liter of this 85% by mass solution?
A 85% (w/w) Phosphoric acid means that 100 g of Phosphoric acid solution contains 85 g of H3PO4. The density of 85% (w/w) Phosphoric acid is 1.685 g/ml at 25°C which means that the weight of the 1 ml of Phosphoric acid is 1.685 gram at 25°C.
