If the following reaction is carried out with 30.0 g of caco3 and excess hcl, what is the maximum mass of cacl2 that can be produced? caco3 + 2hcl → cacl2 + h2o + co2
33.3g

Now consider the reaction when 45.0 g naoh have been added. what amount of naoh is this, and what amount of fecl3 can be consumed by it?
