Here's a "unhelpful" answer. Write down the formula for each molecule. Add the number of subscripts in each anion and cation (if there is none, assume 1). Take the sun and multiply by 0.4132. For example Co(NO3)3
anion subscript=1
cation subscript=3
Total =4
ions in 0.4132 M= 1.653 g-ions.

none of the above. GEEZ. why don't you try actually asking a HARD question. or better yet, start a science club so that you can have an outlet for your obsession with molecules?
