Suppose we have 6.205 grams of Na2S2O3.5H2O . If the molar mass of Na2S2O3.5H2O equals 248 g/mol (MM = 248 g/mol), calculate the moles of Na2S2O3 used.
*PLEASE GIVE ME YOUR COMPLETE SOLUTION & NOT JUST THE FINAL ANSWER
**Do I have to subtract the MM of 5H2O from the MM of Na2S2O3.5H2O in order to find the MM of Na2S2O3?
