What is the difference between the % error equation and the % yield equation?
% error = (expt-accepted)/accepted

Demonstrate the Aufbau principle on the board using an orbital diagram.
place electrons from bottom levels first and work up to higher levels
If told to make 400 mL of a 0.05 M NaCl solution from solid NaCl how would you set up the problem differently from if you are making the solution from 6M stock solution?
volume x concentration = moles
use molar mass to solve for grams of NaCl\
from a stock solution though... C1V1=C2V2
