Question

Concentration of a 1.1M solution of solution of phosphoric acid in water is

Answer 1

Answer:

I think that Mstr Fabio Spaziani has forgot the equivalent mass. for H3PO4 it equal to 3 betwen the normality and the molarity.

N=nM, the relationship betwen normality and molatity.

entre mes calculs et les siens il y a justement le facteur 3

3.5/1.14= 3.05 it's exactly the coefficient value betwen normality and molarity.
