Question

equivalent and molecular weight of H3 PO 4​

Answer 1

Answer:

The molecular weight of phosphoric acid is; (3+31+16*4)gram/mol = 98 gram/mol. Now EQUIVALENT WEIGHT = 98/3 gram/equivalent = 32.67 gram/equivalents. The EqWt depends on the reaction if one proton to form H2PO4- it's the MW; If 2 protons to form HPO4-2 it's 1/2 the MW; if 3 protons to form PO4-3 it's 1/3 the MW.

Answer 2

Answer:

3+39+64=106 molecular mass

Explanation:

106/3=35.33 equivalent mass

N factor = 3
