Iron(ii) sulfate forms a blue-green hydrate with the formula feso4 ·n h2o(s). if this hydrate is heated to a high enough temperature, h2o(g) can be driven off, leaving the dirty yellow anhydrous salt feso4(sa 18.300-g sample of the hydrate was heated to 300 °c. the resulting feso4(s) had a mass of 9.9993 g. calculate the value of n in feso4 ·n h2o(s).

Acetic acid, hc2h3o2, dissolves and completely dissociates in water and a solvation sphere of water molecules forms around the ions. this solute-solvent interaction
