Please help, I'm desperate. In class we're doing this: http://www.flinnsci.com/media/949103/cf11193.pdf and I don't understand how to find the volume of .5M Na3CO3 20% excess. I don't understand how to find the volume to be able to find the excess. Help, please. This lab is so difficult & it's our first guided inquiry lab.
