This prоblem hаs severаl pаrts: A sоlutiоn containing 145.0 g AgNO3 is mixed with a 0.399 moles of CaCl2 solution to produce AgCl. The other product is Ca(NO3)2. Molar masses: CaCl2 =110.978 g/mol ; AgCl=143.3182 g/mol; Ca(NO3)2=164.086 g/mol 6.022 x 1023 = 1 mol Do not round the molar masses. a. ( 4 points) Write the balanced equation. NOTE: Recall from my videos, if you cannot balance the equation in few minutes, just write a "1" in front of the formulaS and use these coefficients for the rest of the problem. You will lose the points for balancing but if you do the rest of the problems using the 1 to 1 mole ratios correctly, you will not lose points off the other parts of this problem. b. (5 points) Calculate the molar mass of AgNO3 SHOW ALL WORK c. (5 points) Calculate the number of moles of AgNO3 in 140 grams of AgNO3. State the answer in correct significant figures. d. (7 points) How many formula units of silver chloride are formed from 3.90 moles of CaCl2 e. (7 points) How many atoms of calcium are in 5.0 grams of Ca(NO3)2? f. (7 points) How many grams of Ca(NO3)2 are formed when 3.456 grams of AgCl are formed?
