    An unknown metal sulfate is found to be 55.66% SO42 by mass. Assuming that the charge on the metal cation is +3, determine the identity of the cation 1. 2. The unknown metal sulfates are hygroscopic and will absorb water from air. They must thus be kept in desiccators to remove any absorbed water and keep them dry. How would your results be affected if your unknown sample was not desiccated? Would you obtain a hig her or lower mass...
