This is the final question on the study guide thats helping me study for finals next week. I am really stuck! I would really appreciate some help. Here is the problem:
For an experiment, a biology student makes 1 liter of a solution containing the following substances:
NaCl
KCl
C6H12O6
NaHCO3
CaCl2 --> 2H2O
MgSO4
NaH2PO4 --> H2O
For each substance, provide the formula weight and (b) calculate either the mass the student needs to weigh out and the number of moles that the student has, based on the amount weighed out.
Be sure to include the formula mass of water for CaCl2 --> 2H2O and NaH2PO4 --> H2O.
