11.7g of NaCl is mixed in solution with 10.2g of AgNOX3: NaCl+AgNOX3AgCl+NaNOX3 (Na = 23, Cl = 35.5, Ag = 108, N = 14, O = 16). Find the mass of AgCl precipitated in grams, to two decimal places.
Numerical answer type, answer in g, tolerance 0.005.
Answer: 8.61 g
n(NaCl)=11.7/58.5=0.200; n(AgNOX3)=10.2/170=0.0600. AgNOX3 is limiting, giving 0.0600 mol AgCl (M=143.5). Mass =0.0600×143.5=8.61g.
