Approximate atomic mass of an element is 26.89 if it's equivalent mass is 8.9, the exact atomic mass of the element would be?

Solution:

The equivalent weight of an element is the mass of a given substance which will supply or react with one mole of hydrogen cation H⁺ in an acid-base reaction. Thus, if equivalent weight of element is 8.9 and approximate atomic mass of this element is 26.89 the equivalent of element is approaching 26.89/8.9=3.021. Since, the equivalent of an element is only whole number, by definition, exactly the atomic mass of the element is: 8.9·3=26.7.

Answer:

Exactly the atomic mass of the element is 26.7.
