Answer to Question #286501 in General Chemistry for kaye

Question

Silver nitrate solution reacts with calcium chloride solution according to the equation: 2

AgNO3 + CaCl2→ Ca(NO3)2 + 2 AgCl. all of the substances involved in this reaction are

soluble in water except AgCl, which forms a solid at the bottom of the flask. Suppose we

mix together a solution containing 6.30 g of AgNO3 and one containing 4.20g of CaCl2.

How many moles of AgNO3 are there in the given amount of AgNO3? _____

Atomic masses: Ag = 107.87, N = 14.01, O = 16.00, Ca = 40.08, Cl = 35.45

Answer 1

Molar mas of Ag NO$_3=(107.87)+(14.01)+(16×3)$

$=169.88g$

Moles of AgNO$_3=\frac{6.30}{169.88}$

$=0.037085\>moles$
