Question

how many miles of NaCl are in a 737 gram container of NaCl?

Answer 1

Answer:

12.61 mol of NaCl

Explanation:

To convert from grams of NaCl to moles of NaCl we need to multiply by the molar mass of NaCl. If you look at your periodic table this value and combine the values of Na and Cl the overall value is 58.44 g/mol.

So lets start off with what we know:

$\frac{737g(NaCl)}{1}$

So if we want moles we need our grams to cancel out and the only way to have that happen is so have our grams on the bottom! So we can say:

$(\frac{737g}{1}) (\frac{mol}{58.44g})$ as you can see our grams cancel out and we are left with units of moles.

So now if we divide 737 by 58.44 we get 12.61 and hence our answer is 12.61 moles.
