64.36 g of an unknown cobalt(II) chloride hydrate was dehydrated in a crucible. The final mass of cobalt(II) chloride was 45.44 g. Calculate the mass of water lost and convert this into number of moles of water lost. a) b) c) Calculate the number of moles of CoCl2 remaining in the crucible. Determine the ratio of moles of water lost (waters of hydration) to moles of CoCl2 remaining. (note, this is just dividing the moles of water lost by the moles of CoCl₂ remaining)
