Molarity, M, has the units mol·L-1, so we want to convert 38g ·100mL-1 to mol·L-1. We will use unit analysis to do this. First, however, let's convert mL to L: 38g . 100mL × 10 . 10 = 380g . 1,000mL = 380g. 1L Since we need to convert from grams to moles, we will need to use the molar mass of NaCl, which is 58.5 g·mol-1
