Lesson 11

Lesson 11 was really short! Basically all you need to know is that molar mass values allow you to convert between mass (g) and moles of a substance. In order to do this, you divide the mass of a sample by the molar mass, to convert moles to mass, you multiply the number of moles of the substance by its molar mass. Use the chart for this!!
