5. Selenite (SeO32") has a central selenium atom to which the other atoms are bound. Draw the Lewis Dot structure that obeys the octet rule. Next draw a Lewis Dot structure that obeys the formal charge rule and draw all the other resonance structures possible. Choose one of the resonance structures and clearly label the formal charges of all the atoms. Choose one of the three oxygen atoms on your resonance structures and clearly label on each structure whether that oxygen has a single, double or triple bond.

An IV bag contains 0.4979 mol of NaCl and a total volume of 2.974 L. What is the concentration of the IV in mass per volume (m/v) percentage? Be sure to express your answer to the correct number of sig figs and include units.

Please show work, just like I need to put it in. Make clear HOW you got to that answer. Please write neat & make it readable. Again please write like I would need to put it in!

attached is a lab. I have all the answers. Can someone just write a nice introduction for this lab for me!! thank you

Use the data in the table below to plot a standard curve (this must be submitted with the problem set) and determine the concentration of the unknowns if possible (Graph paper from the back of the lab manual must be used to create the standard curve). If it is not possible to determine the concentration of the unknown(s), state why and what you would need to do (explain in detail) in order to determine the concentration of the unknown(s). If the concentration of the unknown(s) can be determined, clearly illustrate this on the graph and clearly explain how you determined the concentration of the unknown(s).       SAMPLE PROTEIN  CONCENTRATION ABSORBANCE,  610 nm Standard 1 1 mg/ml 0.064 Standard 2 2.5 mg/ml 0.154 Standard 3 5 mg/ml 0.304 Standard 4 7.5 mg/ml 0.449 Standard 5 10 mg/ml 0.613 Unknown A   0.850 Unknown B   0.475
