Fun with Solutions. Now that you have finished your quiz you are ready to move on to something a little more fun. What could be more fun that doing stoichiometry? No , seriously. You have 2 solutions that you are going to mix together. 19.8 g of KCl in 100. mL H 2 O
Fun with Solutions
KCl (aq) + CaCl2 (aq ) → KCl (aq) + CaCl2(aq)
Aha! The products are the same as the reactants so there IS no reaction.
mol Cl- in CaCl2 = 26.5 g CaCl2 x 1 mol CaCl2 x 2 mol Cl- = 0.478 mol
110.98 g CaCl2 1 mol CaCl2
In total you have 0.266 mol + 0.478 mol = 0.744 mol
Of chloride that is.
