Answer to Problem 3RQ
Two possible conversion factors are
Explanation of Solution
If x number of atoms needed to be converted to mole then it can be written as mole
If number of units present x mole is required then it can be written as number of units
c)
Interpretation :
The conversion factor used to determine moles Al from atoms Al and atoms Au from moles Au must be explained.
Concept Introduction :
To get number of atoms from moles of any element Avogadro’s number is multiplied with the number of moles. To get number of moles from number of atoms of an element, the number of atoms is divided with Avogadro’s number.
