What is the equivalent weight of H3PO4?
32.67 gram/equivalents 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.
What is the molecular mass of H3PO4 in amu?
97.98 atomic mass units For example, the formula mass of phosphoric acid, H3PO4, is 97.98 atomic mass units (amu), which is obtained by adding the atomic masses (taken from the periodic table) of the elements in one formula unit (i.e., 3 H + 1 P + 4 O).

How do I calculate molecular weight?
Sample Molecular Weight Calculation Using the periodic table of the elements to find atomic weights, we find that hydrogen has an atomic weight of 1, and oxygen's is 16. In order to calculate the molecular weight of one water molecule, we add the contributions from each atom; that is, 2(1) + 1(16) = 18 grams/mole.
What is the equivalent weight of H 3 PO 2?
(D) 49.5. Hint: As we know that in a chemical reaction the equivalence of a substance is explained as the amount of which combines with 1 mole of the hydrogen atoms or replaces the same number of hydrogen atoms in the reaction. Thus equivalent weight in grams is the weight of 1 grams.
