First, write the balanced equation for the reaction.
Scores
AGNO3 (aq) + KCI(aq) → AgCl(s) + KNO3(aq)
Pearson eText
Next, calculate the moles of the known substance, KCI, by dividing the given mass, after converting from mg to g (1000 mg =1g), by its molar mass, 74.55 g/m
multiply by the mole ratio from the balanced equation, 1:1, to convert from mol KCl to mol AGNO3. Finally, convert mol AgNO3 to M AgN03 using its given vo
converting from mL to L (1000 mL =1L).
