so (4.8e-2*30.0mL)=1.44 (3.6e-2*21.5mL)=.774 now what do I do
April 27, 2010

chemistry
I did: (4.8e-2*30.0mL)/1000mL=.0014 (3.6e-2*21.5mL)/1000mL=7.74e-4 Then I added the two to get .005474 then divided that by the total L to get .106 I then took the -log(.106) to get .975, but that's the wrong answer
