I'm confused about this question.. It says If 20 mL of .012M soln. of Ca(OH)2 is added to a 48 mL of HBR, what is the concentration of the HBr?
The answers say not to use M1V1=M2V2. Instead use Normality. SO NaVa=NbVb
Na[48]=.024(20) This is where I'm confused about where the .024 came from because when you find the moles ... you get .012M(20mL)=.24mol and then in the problem they use .024... where did that come from?
Thanks!
