Quantitative Chemistry question... titrations?

ncffa_edavis · #1 (**permalink**) 03-29-2008, 11:45 PM

1. If the titrant has a molarity of 0.2000 M and there are 10.00 mL of analyte present, what is the molarity of the analyte?

What is the pKa of the analyte in this titration to the nearest 0.5?

2. If the titrant has a molarity of 0.1250 M and there are 20.00 mL of analyte present, what is the molarity of the analyte?

If 0.4575 g of analyte were dissoved in 20.00 mL of water to perform this titration, what is the molecular mass of the analyte?

I just can't figure it out! I have three of them. If you can explain one, I might be able to do the others.
Thanks!

There seems to be some info missing.
