Cobalt(II) chloride can be prepared by the reaction of cobalt(II) carbonate with aqueous hydro- chloric acid according to the equation CoCO3(s) + 2HCl(aq) → CoCl2(aq) + H2O(l) + CO2(g) The cobalt(II) chloride crystallizes from solution as a red-colored hexahydrate, CoCl2·6 H2O(s). How many grams of CoCl2·6H2O(s) can be prepared by reacting 100.0 milliliters of 0.375 M HCl(aq) with 2.17 grams of CoCO3(s)?
