Homework Help: Ap Chemistry

Posted by Norman on Tuesday, April 22, 2008 at 5:04pm.

Hi, I'm working out this question for homework, but i'm a little stuck.

How many g of sodium hydrogen carbonate (NaHCO3) and 4.836 g of sodium carbonate must be dissolved in 750 mL of H20 in order to make a buffer with a pH of 10.27??

the ka of sodium hydrogen carbonate is 5.6 x 10 ^11

here is what i did:
4.836 g NaCO3(1 mol/105.99 NaCO3) = 0.04563 mols NaCO3

0.04536 mols/.750 L = 0.0608 M Na2CO3

Am i on the right track? What do i do next? Thanks, I'm completely at a loss for what to do next.
