Ответ:
We need to convert the amounts of the reactants into moles to see the limiting reactant.
48.2 g HCl ( 1 mol / 36.46 g) = 1.32 mol HCl
Since the ration is 1:4 then the limiting reactant is HCl. To react all of the MnO2 we need 3.44 mol HCl.
How many grams of Cl2 will be produced?
We use the amount of limiting reactant since it will be used up first.
1.32 mol HCl (1 mol Cl2 / 4 mol HCl) ( 70.9 g Cl2 / 1 mol Cl2) =23.4 g CL2
