Answer:

Approx. #0.2*mol#.

Explanation:

There are 2 equiv hydroxide ion per equiv of magnesium hydroxide; and thus moles of hydroxide,

#=2xx(5*g)/(58.32*g*mol^-1)=0.188*mol# WITH RESPECT TO HYDROXIDE IONS. What would be the #pH# of a solution of this material if we made up the volume to #1.00*L#?
