You need 3.5L of 50mM NaCl from your 20X stock. How would you accomplish this:
20X stock __________ml
Pure Water ___________ml
From whatever number I plugged in trying to solve it, I got: 175ml of 20X stock and 3,430ml of Pure Water. Have no idea if those are right. Any help is appreciated.

I'm not sure either.
