Convert the given temperatures.  a. 77 °F = [cel] °C   b. 325 °C = [farh] °F 

Determine which of the following is larger:  a. 1 gram or 1 milligram? [larger]   b. 1 milligram or 1 kilogram? [larger2]   c. 1 milligram or 1 microgram? [larger3]

Write the abbreviation for each quantity:  a. We would abbreviate 65 milligrams as 65 [milligrams].  b. We would abbreviate 125 kilolitres as 125 [kiloliters].  c. We would abbreviate 82 centimeters as 82 [centimeters]. 

Complete the following conversions.  a. 1 m = [mm] mm    b. 1 cm = [m] m    c. 1 mm = [m2] m    d. 1 cm = [mm2] mm    e. 1 m = [km] km 

Write the SI (metric) unit for each abbreviation given below.  a.  18 m represents [m]    b. 15 L represents [L]    c. 85 mm represents [mm]. 

Which solution of NaCl is more concentrated, as labeled?

You extracted RNA using the organic solvent method (Trizol, which uses phenol and chloroform to extract this molecule). You measured your extracted sample and the A260/A280 ratio is 1.7. You would describe this preparation as:

You need 250 mL of 0.25X tris-acetate-EDTA (TAE) for the buffer tank to run an agarose slab gel. You have 50X stock TAE. How much of the stock TAE do you need to dilute to 250mL?

After weighing the masses of Tris and EDTA you calculated in the previous question, you dumped the powders in a standard lab beaker, added ddH2O to the 100mL mark on the beaker and stirred until the powder was completely dissolved. Is this solution correctly made and ready for use as described (yes or no)? Justify your answer.
