1259 2 0 349H₂ = $.675 mol 10. A 5.95-g sample of AgNO3 is reacted with excess BaCl2 according to the equation 2AgNO3(aq) + BaCl2(aq) + 2AgCl(s) + Ba(NO3)2(aq) to give 4.48 g of AgCl. What is the percent yield of AgCl?
A 0.2150 g sample is dissolved and treated with excess AgNO3. The precipitate is filtered, washed, dried, and weighed. The mass of the product (AgCl) is 0.4587 g. What is the wt% of Cl in the original sample? The molecular weight of AgCl is 143.32 g/mol.
CaCl2 reacts with AgNO3 in aqueous solutions to produce a precipitate of AgCl that can be filtered and weighed. The balanced equation for the reaction is: CaCl2 (aq) + 2 AgNO3 (aq) → 2 AgCl (s) + Ca(NO3)2 (aq) Suppose you have a mixture that contains CaCl2, plus other compounds that do not react with AgNO3. If 0.2918 g of the mixture yields 0.4462 g of AgCl, what is the percentage of CaCl2 in the mixture? Molar masses: CaCl2 110.98...
