Hоld yоu scrаp pаper аnd periоdic table (if you printed it out) up to the camera. Be sure to show both sides. Show your entire desk area to the camera. Acknowledge that you are taking this test fairly without notes, assistance from another person, or the assistance from any electronic devices (except scientific calculator). If it is later found that you are in violation of the above you will receive a zero for this exam and you will be reported to the academic integrity office at SPC. Below you shall find useful information: Density = Mass/ volume Molarity = Mole/Volume Idea Gas Law: PV = nRT R = 0.08206 Changing Conditions of Gas: P1V1/T1 = P2V2/T2 1atm = 760torr = 760mmHg
