I need help on this problem.

Question

So I have is 8.56 x 10^-3 moles of NaCl are equal to how many grams of NaCl?

help is needed.

Answer 1

To solve this, we need to find the molar mass of NaCl by adding the masses of Na and Cl from the periodic table. Doing this, we find a molar mass for NaCl of 58 g/mol. Now, we simply multiply that mass by the number of moles we were given to cancel out the mol unit and be left with only grams.

58 g/mol x 8.56 x 10^-3 mol = 0.496 grams of NaCl

Hope this helps!
