Review the relationship between concentration and amount. Classify each of the following units as either a concentration or an amount: mg, nanomoles, mg/mL, 1% (w/v), mM, ppm.

How do you convert between concentration and amount? Answer the following questions in your lab notebook. Also classify each as either going from an amount to a concentration or as going from a concentration to an amount.

We have a solution of 12 mg cholesterol/mL. What volume contains 3 mg of cholesterol? How many millimoles galactose are present in 250 mL of a 5 mM solution of galactose? How many milligrams of starch need to be dissolved in 10 mL of water to make a 5% (w/v) solution? We dissolve 15 moles of glucose in 5 mL of water. What is the concentration of this solution in M? What is the concentration of this solution in g/mL?

Calculate the volumes of BSA standard that you'll need to build your standard curve and record this information in your lab notebook. Record one example calculation so I can follow your work.
