Answer to Question #103536 in General Chemistry for shane wagner

Question

what is the molarity of a CuCl2 in a solution prepared by dissolving 92 g of CuCl2 in enough water to yield a 1.60 L of solution

Answer 1

Molecular Weight of CuCl2 = 134 gm/mole

If 134 gm of CuCl2 is dissolve in 1000ml i.e 1L soution then the molarity of the solution is 1M

Therefore using unitary method the molarity of the solution is =

= (92*1)/(194*1.6)M

=0.3 M
