Concept introduction:
Number of moles of a compound is defined as the ratio of given mass of the compound to the molar or molecular mass of the compound.
The mathematical expression is given by:
Number of moles =
The one mole of any substance is equal to the
Explanation of Solution
Since, one mole of any substance is equal to the Avogadro number i.e.
Number of moles =
Thus, first step is to convert the number of molecules/atoms into number of moles with the help of above formula. After that, multiply the number of moles with molar mass of the element to obtain the mass of the given element.
The mathematical expression for the calculation of number of moles is:
