How do I do this? Thank you so much for the help. I have numerous questions on my homework like this one so steps are much appreciated! When solutions of silver nitrate, AgNO3, and calcium iodide, CaI2, are mixed, a yellow precipitate of silver iodide is formed. Calculate the mass of silver iodide that is formed if 50.00 mL of 1.00 M AgNO3 is combined with 30.00 mL of 1.25 M CaI2.
