Answer:
[tex]8.432 * 10^{23}[/tex] molecules
Explanation:
As per Avogadro's constant for atoms, one mole of an element/compound consists of [tex]6.023 * 10^{23}\\[/tex] atoms/molecules.
Thus, the number of molecules in “n” moles of an element and compound is equal to the product of number of moles of the element and compound and Avogadro's constant.
Thus, 1.4 moles of [tex]N_{2}[/tex] will have
[tex]1.4 * 6.023 * 10^{23}[/tex] molecules
[tex]= 8.432 * 10^{23}[/tex] molecules
