WebThe molecular weigh of H 3PO 3 is 98. Phosporic acid is di basic acid. So the equivalent weight is 98/2=49. Hence option B is correct. WebThe molar mass is a physical property defined as the mass of a given substance (chemical element or chemical compound) divided by the amount of substance. The molar mass of atoms of an element is given by the standard relative atomic mass of the element multiplied by the molar mass constant, 1 × 10−3 kg/mol = 1 g/mol. WebEquivalent Weight of H 3 P O 3 = B a s i c i t y M o l e c u l a r w e i g h t o f H 3 P O 3 (M) Since, H 3 P O 3 is a dibasic acid i.e it has two hydrogen ions to donate to a base in acid - base reaction. cummings auto
