Anyone really good at acid/bases? I could use some help with one or two things, please email me if you think you can help. 
THANK YOU to everyone who responded. It turned out I was doing the problem right all along but didn’t know it. I over think things sometimes (note to self: do NOT do that on the MCAT!).
Thank you again, and be warned, I will have problems in future and will ask you all again…
