1. These are just unit changes? What is the problem you are having?
2. mass = volume x density. Substitute and solve for mass.
3. I'm confused; you used molecules in two different ways.
1.what is the volume of NaCl in cubic cm and cubic nm if the Length is 0.563 nm?
2. the density of NaCl is 2.17 g/cm. What is the Mass?
3. Each repeating unit is composed of 4 NaCl molecules. What is the Mass of 1 NaCl molecule?
