Question

calculate the molarity of 20g of CaCo3 in 100ml solution?

Answer 1

We have to find molarity of solution

◈ What is molarity (M) ?

Molarity is defined as the ratio of no. of moles of solute (dilute in solution) to the volume of solution in L

Unit :- mol/L

Molar mass of solute = 100g/mol

Moles of solute = 50/100 = 0.5

⇒ M = mole/volume

⇒ M = 0.5/0.5

⇒ M = 1 mol/L
