## What is the mass of 1 mol of CaCO3?

390 Unit 6 Changes in Matter The formula mass of CaCO3 is 100.09 amu and, therefore, the molar mass of one mole of CaCO3 is 100.09 grams.

## How many molecules of CaCO3 are present in its 1 mole?

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?
