Preparing buffer solns.

... Anyway, here's an example of what I'm trying to do. Given: 10x TAE- 0.4M tris, 0.2N acetic acied, 10mM EDTA Prepare: 500mL of tris (MW=121.1g), glacial acetic acid (17.46N), 0.5M EDTA Also, prepare 1L of 1xTAE. So far, I have just converted the molarity of Tris to moles and then to grams by ...
