In 1 mol of NaCl there are 58.44 g. So 58.44 xx ????

Explanation:

We have a formula mass in g*mol^-1, and a 14.65 mol quantity of NaCl.

The mass is simply the product: 14.65*cancel(mol)xx58.44*g*cancel(mol^-1) = ???g.

When we use units in the calculation like this, we introduce an extra safeguard in that if the answer simplifies to moles we know we have not divided when we should have multiplied.
