Samples of hydrated manganese perchlorate are heated to determine the amount of crystal water:Mn(ClO4)2·nH2O ! Mn(ClO4)2 + nH2OTwo samples of different weight are studied:a) m (before heating) = 1.629 g ; m (after heating) = 1.142 gb) m (before heating) = 9.048 g ; m (after heating) = 6.645 gFor both samples, calculate the number of moles of crystal waterper formula unit of manganese perchlorate. Decide which sample is most likely to represent the correct result, and explain what might have gone wrong with the other.
