How do i convert mols CaCl2 to AgCl

In the equation for that process we had

2AgNO3 + CaCl2 ==> 2AgCl + Ca(NO3)2

You convert anything to anything using the coefficients in the balanced equation. Let's just suppose you had 0.1 mol CaCl2 (I don't remember the numbers) so we want to convert 0.1 mol CaCl2 to ? mols AgCl.
0.1 mol CaCl2 x (2 mols AgCl/1 mol CaCl2) = 0.1 mol x 2/1 = 0.2 mols AgCl.
