Question

This is the given question: 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.

Answer 1

this is the chart i completed i didnt know how to put the chart on here so just know all the numbers correspond with one another

substances:
1. NaCl
2. KCl
3. C6H12O6
4. NaHCO3
5. CaCl2 * 2H2O
6. MgSO4
7. NaH2PO4 * H2O

formula weights: (g/mols)
58.4
74
180.2
84
107.01
246.47
120.4

number of moles:
1. 0.14
2. 0.005
3. .75
4. 0.0262
5. .01173
6. 0.0008
7. .0033

mass (g)
1. 58.5
2. 74.55
3. 1.01
4. 84.01
5. 0.15
6. 120.336
7. 0.14

Can anyone please show me how to show work?? I do not understand this unit well at all. I would really appreciate it if you could give me an example of how to show work 1 for finding the formula weight, one for finding the number of moles and one for the mass. Please I really need help!! Thank you
