I would like help solving this problem in unit conversion fashion.

Hi. I am trying to calculate the percent of water in an uknown hydrate. The given data is: mass of empty crucible +lid = 27.19g   mass of crucible + lid and hydrate = 28.58g   mass of crucible + lid and sample after heating(anhydrous salt) = 27.68g     % water in hydrate formula = mass of water/mass of hydrate * 100
