Admin

What is the equivalent weight of H 3 PO 4?

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.

How do you calculate equivalent weight?

Equivalent Weight = Molecular weight/ Valency Also, read: Chemical Reaction.

How do you find the equivalent weight of na2co3?

Answer: 53 g/eq

  1. Na : 2 x 23.0 = 46.
  2. C : 1 x 12.0 = 12.
  3. O : 3 x 16 = 48.

What is the equivalent weight of nah2po4?

Thus, the equivalent mass of $\text{Na}{{\text{H}}_{2}}\text{P}{{\text{O}}_{4}}$ is 120 grams, So, the correct answer is “Option C”. Note: The number of replaceable hydrogen atoms means the basicity of compound 1 minus the basicity of compound 2.

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.

How do you find the equivalent mass of H 3 PO 4?

Step-By-Step answer: Molar mass of ${H_3}P{O_4}$ $ = 3 \times $ atomic mass of hydrogen $ + $ atomic mass of phosphorus $ + 4 \times $ atomic mass of oxygen $ = 3 \times 1 + 31 + 4 \times 16 = 98$ gram per mole. Since here two hydrogen ions are replaced in the reaction so n factor is two.

How do you calculate equivalent weight from normality?

Normality Formula

  1. Normality = Number of gram equivalents × [volume of solution in litres]-1
  2. Number of gram equivalents = weight of solute × [Equivalent weight of solute]-1
  3. N = Weight of Solute (gram) × [Equivalent weight × Volume (L)]
  4. N = Molarity × Molar mass × [Equivalent mass]-1
