Answer:
[tex]1.03\text{ moles}[/tex]Explantion
Here, we want to get the number of moles in 60 g sample of NaCl
Mathematically, to get this, we have to divide the mass given by the molar mass of NaCl
Thenmolar mass of NaCl is 58.44 g/mol
Thus, we have the number of moles as:
[tex]\frac{60}{58.44}\text{ = 1.03 mole}[/tex]
