If I need to find q, when q=m x s x delta t, of the addition of 4.012 g of solid NH4Cl to 100 mL of H2O, would my mass be just the 4.012 since NH4 and Cl dissociate? Or would it be 104.012 since I would have to include the mass of the water? Could you also include the equations for the answer to help me understand how you got the answer? Thank you!

How do I find the weight precent iron (II)? We measured 1.0014 g of unknown iron sample and added 100.0 mL water. Then pipetted 10.00 mL of the first solution into a beaker and added 90.00 mL of water. Then added 1,000 microliters of the second solution to a plastic container along with the reagents needed to analyze it with a spectrophotmeter. This solutions total volume was 10.00 mL. I then measured the absorbance of this solution and got .019...
