    I need help with this chemistry question on moles?

    Mr AgCl = 108+35.5 = 143.5 1.050 g of silver chloride = 1.050 g AgCl = 1.05/143.5 = 3/410 moles of AgCl mol of Ag = mol of Cl = mol og AgCl = 3/410 mol We know that the total mol of AgCl is constant during both reaction, so total mass of Ag = 3/410 * 108 = 162/205 gram percentage of silver...
