Unformatted text preview: A hypothesis when tested will allow you to explain how and why something works. 3. The base units for the metric system easily convert to one another and have prefixes that are multiples of 10, making them easy to manipulate. 4. Perform the following calculations: a. 3 meters = 300 centimeters (cm) b. 20 centimeters = 200 millimeters (mm) c. 1 Liter = 1000 milliliters (mL) 5. Molecular mass is the total of all the mass in a molecule. To find the weight of C6H12O6 you would add the weight of 6 carbon atoms to 12 hydrogen atoms and then add the weight of 6 Oxygen atoms. 6. Buffers prevent swings in pH by accepting H+ ions or giving off OH- ions. Buffers work to maintain the pH so enzymatic reactions occur at optimal levels....
