A chemist adds of a M sodium thiosulfate solution to a reaction flask. Calculate the millimoles of sodium thiosulfate the chemist has added to the flask. Be sure your answer has the correct number of significant digits.
The formula for sodium thoisulphate is Na2S2O3.5H20 with the molar weight of on Na=23,S=32, O=16, H=1 multiply their weight by the coefficient then 18 by 5 then the in millimole is equals M/248 X 10^-3
