Question
Milk of Magnesium (Mg(OH)2(aq) )is used to nuetralize stomach acid(HCl(aq)). Mg(OH)2(aq) + 2HCl----->2H2O(l) + MgCl2 5.50g ? My professor posted this question. I'm not sure what he'sasking for. I know that he put 5.50 grams underneath theMg(OH)2(aq) and the question markunderneath 2HCl. Milk of Magnesium (Mg(OH)2(aq) )is used to nuetralize stomach acid

Explanation / Answer
I think your professor want you to find the number of moles or massof HCl needed to react with 5.5g of magnesium hydroxide n(Mg(OH)2) = m/M = 5.50/58.326 = 0.094298mol n(HCl) = 2/1 x n(Mg(OH)2) =0.1886mol m(HCl) = nM = 0.1886 x 36.458 = 6.88g Hope this helps!
