So the dilution factor between 1.2 microgram/mL and 1.8 mg/mL is 1500. Expressed another way, it is a 1:1500 dilution (which = 0.000666…., as you saw! Though it doesn’t have units). I’m not certain what you are saying about your professor. Sometimes low dilutions are expressed as the amounts to add, rather than the final volume. Jan 04, 2016 · On Question #4 of the Dilution Review section of the "Solutions Review Worksheet," I knew that I had to use the M 1 V 1 =M 2 V 2 formula. I multiplied the final molarity (0.3 M) by the final volume (300 mL), and I divided that product by the initial molarity (6.0 M) to calculate the initial volume.
