1. For an experiment, a biology student makes 1 liter of a solution containing the following substances, which are shown in the table below. Using the given information, fill in the missing parts of the table for each substance by (a) providing the formula weight and (b) calculating either the mass the student needs to weigh out or the number of moles that the student has, based on the amount weighed out. For each calculation, show your work. Be sure
to include the formula mass of water for CaCl2 * 2H2O and NaH2PO4 * H2O.
Substance Formula Weight (g/mol) Number of Moles Mass (g)
NaCl 0.14
KCl 0.005
C6H12O6 1.01
NaHCO3 0.0262
CaCl2 * 2H2O 0.15
MgSO4 0.0008
NaH2PO4 * H2O 0.14
