To find the equivalent weight of an acid, divide its molar mass by the number of protons (H⁺ ions) that the acid can donate in a reaction. For example, for sulfuric acid (H₂SO₄), the molar mass is approximately 98 g/mol, and since it can donate two protons, its equivalent weight is 98 g/mol ÷ 2 = 49 g/equiv. This approach applies to other acids by adjusting the number of protons they can donate.

If you have molecular weight how can you find equivalent weight?
To determine the equivalent weight from the molecular weight, you need to divide the molecular weight by the valence (or charge) of the compound. For example, for a compound with a molecular weight of 100 g/mol and a valence of 2, the equivalent weight would be 50 g/equiv.
Which of the following has same equivalent and molecular weight?
If two substances have the same equivalent weight, it means the number of equivalents per mole is the same for both substances. Therefore, the molecular weight of these substances would also be the same, as equivalent weight is derived from the molecular weight and valence of the substance.

How do you find equivalent weight of CaO?
To find the equivalent weight of calcium oxide (CaO), divide its molar mass by the number of moles of replaceable ions it provides in a reaction. The molar mass of CaO is approximately 56.08 g/mol. Since CaO dissociates to release one calcium ion (Ca²⁺) per formula unit, its equivalent weight is the same as its molar mass, which is 56.08 g/equiv.

Equivalent weight of NaHPO4?
The equivalent weight of NaHPO4 is determined by calculating the molecular weight divided by the change in oxidation state per reacting equivalent. For NaHPO4, the molecular weight is 137.99 g/mol, and it can donate 1 equivalent of H+ or accept 1 equivalent of OH-. Therefore, the equivalent weight of NaHPO4 is 137.99 g/mol.
The amount of air pressure on your body is equivalent to the weight of?

What is the formula of equivalent weight?
Equivalent weight = Molar mass of a substance/electrical charge of the ions (positive or negative) formed in solution Also the equivalent weight of a substance react with 1 mole of hydrogen. Today this expression is rarely used.
