How to calculate the pH of the solution if 150 mL of hydrochloric acid is consumed to complete the raction with the magnesium, with a total concentration of 0.45 #"mol / dm"^-3#?
#MgO(s ) + 2HCl(aq ) -> MgCl_2(aq ) + H_2O( l) #

Well, at equivalence the solution is stoichiometric in
Explanation:
And thus
It is likely that the question asks as to the MASS of magnesium oxide that was decomposed by the acid....
And you have provided the stoichiometric equation...
Now with respect to hydrochloric we used a molar quantity of...
And so WITH RESPECT TO magnesium oxide, there was a mass of...
If I am barking up the wrong tree, I apologize....
