Numerical problems based On Mole Concept

Calculate the mass of 6.022 × 1023 molecule of Calcium carbonate (CaCO3). Solution — Molar mass (Molecular mass in gram) of CaCO3 = 40+12+3×16 = 100 g No. of moles of CaCO3 = No. of molecules/Avogadro constant = 6.022 × 1023/ 6.022 × 1023 = 1 mole Mass of CaCO3 = No.

What is the molarity of CaCO3?

The molarity of a calcium carbonate (molar mass = 100. g/mol) solution is 2.4 x 10 ^-3 .

How is CaCO3 calculated in CA?

calcium carbonate (CaCO3) equivalent

Alkalinity test results are usually reported as mg/L CaCO3 equivalents. To convert chloride to CaCO3 equivalents, multiply the concentration of chloride ions in mg/L by 1.41, and for sulfate, multiply by 1.04.

How do you find the equivalent weight of CaCO3?

The equivalent mass of CaCO3 is 100g/2=50g.
