The element that has the higher number of atoms is to be determined in given elements. Concept Introduction: The molar mass of a substance is the mass of that substance present in one mole of it. A mole is a quantity used to express a very large number of atoms or molecules. One mole of a substance is equal to 6.022 × 10 23 , that is, Avogadro’s number . The moles of a substance are expressed as: n = m M Here, m is the mass of the substance, M is the molar mass, and n is the number of moles. The mass of a substance is given by the expression m = M n The relationship between moles of a substance and number of atoms can be expressed as 1 mole = 6 .022 × 10 23 atoms To convert moles into number of atoms, conversion factor is 6.022 × 10 23 atoms 1 mol .

Interpretation Introduction
Interpretation:
The element that has the higher number of atoms is to be determined in given elements.
Concept Introduction:
The molar mass of a substance is the mass of that substance present in one mole of it.
A mole is a quantity used to express a very large number of atoms or molecules. One mole of a substance is equal to 6.022×1023, that is, Avogadro’s number.
The moles of a substance are expressed as: n=mM
Here, m is the mass of the substance, M is the molar mass, and n is the number of moles.
The mass of a substance is given by the expression m=Mn
The relationship between moles of a substance and number of atoms can be expressed as 1 mole = 6.022×1023atoms
To convert moles into number of atoms, conversion factor is 6.022×1023 atoms1 mol.
For the titration of a divalent metal ion (M2+) with EDTA, the stoichiometry of the reaction is typically:
1:1 (one mole of EDTA per mole of metal ion)
2:1 (two moles of EDTA per mole of metal ion)
1:2 (one mole of EDTA per two moles of metal ion)
None of the above
