Question

In the reaction MgCl2 + 2KOH Mg(OH)2 + 2KCl, how many moles of Mg(OH)2 are produced for every mole of MgCl2?

Answer 1

The stoichiometric equation above is given. We make sure that the balancing of the equation is correct by checking all the elements. From the balanced reaction, every mole of MgCl2, there is one mole of Mg(OH)2 produced. Hence, there is a one to one ratio correspondence.
