Question

what is a relation between molarity and strength?​

Answer 1

strength= molarity × molecular mass

Normality × equivalent mass = strength of solution in g/L. Formality: Formality is the number of formula mass in gram present per litre of a solution. If the formula mass of solute is equal to its molar mass, then the formality is equal to molarity.

Answer 2

Answer:

Molarity × Molar Mass = Strength

Explanation:

We know,

Molarity = No. of moles of solute

Volume of solution (litres)

No. of moles = Given mass

Molar Mass

So, expression becomes:

Molarity = Given Mass

Molar Mass

Volume of Solution (in litres)

Now, Given mass. = Strength

Volume of solution

So, Molarity = Strength

Molar Mass

So, Molarity × Molar Mass = Strength.

Hence, proved.
