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.

anyway this is an old question but

for each substance, calculate the formula weight by adding up all the molar masses of its constituent atoms

from there, for any rows where you're given moles, multiply moles * molar mass of the compound to get grams

for the other rows, where you're given grams, divide grams/molar mass of the compound to get moles
