Please solution give me part C

 

A) 9.76 g of KOH is put into a 100. ml volumetric flask and DI water is added until the resulting
solution reached the line on the flask. What is the molar concentration of this solution?
Mol
569
B) If 31 mL of the previous KOH solution (2A) was used to make 100 ml of a diluted KOH solution
what will be the new concentration?
(1.742)(31) = (mo)(100) Tna> o Stamey
E) How many ml of the diluted solution (from part 8) will be needed to make 2.0 mg of
precipitate from a reaction with Ca(NO:),?
