Calculate the mass fraction of phosphoric acid in a solution with a molar concentration of this substance of 2M. The density of the solution is 1.1 g / ml.

1. Find the mass of acid in 1 liter of solution = 98 * 2 = 196 grams.
2. Find the mass of the solution = 1000 ml * 1.1 = 1100 grams.
Mass fraction = 196/1100 = 0.1782 or 17.82%.
