Explanation:
Detailed explanation-1: -To calculate the number of atoms first step is to calculate the number of moles. If the mass of an element/compound is given then divide the given mass by the molar mass of the element/compound to find the number of moles. In 1 mole of a substance, the number of atoms is or. 023 × 10 23 atoms.
Detailed explanation-2: -The equation is fairly simple. The number of atoms of ANY substance in a volume is: # of atoms = N * (density) * volume / (Molecular Weight). N is a constant called Avogadro’s number and its equal to 6.022*1023 atoms/mole.
Detailed explanation-3: -Calcium carbonate is a molecule that contains one atom of calcium, one atom of carbon, and three atoms of oxygen.
