Question 1: How many grams of solid NaOH are required to prepare 100ml of a 0.02M solution? (The MW of NaOH is 40).

Question 2: A concentration of 2mg/liter is equivalent to: 0.002 mg/ml 2mg/ml 0.2mg/ml 0.02mg/ml 0.0002mg/ml

Question 3: A concentration of 2mg/liter is equivalent to: 0.002 μg/ml 2μg/ml 0.2μg/ml 0.02μg/ml 0.0002μg/ml

Question 4: How many ml of 2M H2SO4 are required to make 500ml of a 1mM H2SO4 solution?

Question 5: a. You have a 5mg/ml stock solution of cyclohexamide (an inhibitor of protein synthesis). For an experiment you with to do, you need to add cycloheximide to your cells to a final concentration of 25μg/ml. You have 10mls of cells. How much of your stock solution would you add to your cells?

b. What would you do if you needed to have a final concentration of 0.25μg/ml? Pay attention to your answers to question 3.
