Question

31.75/96500 find equivalent wt

Answer 1

Heres how to solve.

Explanation:

Equivalent weight predicts the mass of a substance that will react with one atom of hydrogen in an acid-base analysis such as a titration. You can calculate it easily, as long as you know the molecular weights of the compounds involved in the reaction. The equivalent weight of an element is the mass which combines with or displaces 1.008 gram of hydrogen or 8.0 grams of oxygen or 35.5 grams of chlorine. These values correspond to the atomic weight divided by the usual valence; for oxygen as example that is 16.0 g / 2 = 8.0 g.Examples: (1) H 2 SO 4 + 2OH-= 2H 2 O + SO 4 2-Molecular weight of sulfuric acid (H 2 SO 4) = 98.07 g/mol
