Magnesium bromide is prepared in a laboratory using the reaction
below. Typically, the magnesium bromide is recovered as a solid
by heating away the remaining water.
MgO(s) + 2 HBr(aq) → MgBr2(aq) + H2O(1)
If 0.860 mole of HBr in solution is added to 14.0 grams of MgO in
a beaker and then
is heated until dry, what are the expected contents of the beaker?
