For the following chemical reaction, how many moles of silver iodide (AgI) will be produced from 4 mol of calcium iodide (CaI2)?

1 answer

You don't give a reaction; I assume you just didn't type it into the post. I'll write one.
CaI2 + 2AgNO3 ==> 2AgI + Ca(NO3)2
4 mols CaI2.
Using the coefficients in the balanced equation, convert mols CaI2 to mols AgI.
