A 50 ml sample of 0.025M AgNo3 is mixed with 15 ml of 0.04 M CrCl3. How many grams of AgCl will precipitate? Please show steps

• Chem -

moles AgNO3 = M x L = ??
moles CrCl3 = M x L = ??

Using the coefficients in the balanced equation, convert moles AgNO3 to moles AgCl.
Same procedure, convert moles CrCl3 to moles AgCl.
The two answers likely will be different which means one of them is wrong; in limiting reagent problems the correct answer is ALWAYS the smaller value and the reagent producing that value is the limiting reagent.

Then convert moles AgCl to grams. g = moles x molar mass.
