Answer:
Explanation:
NaCl is the chemical formula of sodium chloride.
Na is the chemical symbol of sodium and Cl is the chemical symbol of chlorine.
The chemical formula shows the ratio of the elements using subscripts to the right of each element.
Thus, a chemical formula [tex]X_aY_bZ_c[/tex] indicates that one mole of compound contains [tex]a[/tex] moles of element [tex]X[/tex], [tex]b[/tex] moles of element [tex]Y[/tex] , and [tex]c[/tex] moles of element [tex]Z[/tex].
When there is not a subscript is because the corresponding subscript is 1.
Therefore, the chemical formula NaCl indicates that 1 mol of NaCl contains 1 mol of Na and 1 mol of Cl.
