Question

chemistry problem. simple. Is this correct?
make 50ml of solution
from:
25mM of tris
50mM of glucose
10mM of EDTA
____________
should I calculate each one seperately..
.025mol/L * .05L * 121 (MW of tris) = .15 g?
And do the other 2 the same way?
I get the answer in g? and then would i combine it all in one beaker then add water?

Answer 1

Your math is correct. The only change I would make is to make the solution in a 50 ml volumetric flask.
