Explanation:
Mass<span> is the amount of matter in an object. Move to a different planet and an object's weight will change, but its </span>mass<span> will be the same. </span>
The expression for the Ka for the given acid is:
Ka = [H2P2O7^2-] [H3O+] /[H3P2O7^2-]
<span>Ka is the acid dissociation constant or the acidity constant. It is a measure of the acid strength when in solution. It is an equilibrium constant for the dissociation of the acid.</span>
