Question

What is the mass of 1.2 x 10^-3 moles of sodium chloride? – Show Work

Answer 1

I will tell you how to find the answer, and you can do the calculations.

1. Find the molecular weight of NaCl (sodium chloride). Look up in your chemistry book the atomic weights of Na and Cl. Add them together, and that will be the molecular weight of NaCl.

2. Multiply the number of moles present by the molecular weight, and that will be the mass in grams of NaCl present. (Remember the molecular weight is the mass in grams of 1 mole of the substance.)
