Make two solutions of 100 ml each: A is 125 mM Na_2HPO_4 times 7H_2O (FW = 268) and B is 0.25 M NaH_2PO_4 (FW = 120). When you mix them in this ratio? (2 parts water, 1 part A, and 0.5 parts B) what will the final molarity be for each one in this mixture. Make 200 ml of a 15 mM Tris, 50 mM EDTA, and 0.03 M NaCl from stock solutions that are 1M Tris, 0.5 M EDTA, and 5000 mM NaCl. You are making a PCR mixture that will be 1 X of all reagents and the final volume will be 200 mu 1. How do you with these stocks? 300X solution A 1500 X B 200X C 25X D
