Answer 1

तुल्यांकि भार मतलब equivalent mass.

मुझे हिंदी में पता नहीं है, इसलिए इंग्लिस में लिख रहा हूँ।

Molar mass of H3PO4 = 1×3 + 31×1 + 16×4 = 1 + 31 + 64 = 98g.

it is given that 3 H atoms can be protonated(विस्थापनिय है)

So you need to divide molar mass by 3 to get equivalent mass.

Equivalent mass = molar mass / 3 = 98/3 = 32.67g

So equivalent mass of Phosphoric acid is 32.67g.

तुल्यांकि भार 32.67 g है
