How many grams of Mg(OH)2 are needed to neutralize 55 ml of 0.25 M HCl .
according to the following reaction. (show all calculations for credit)
Mg(OH)2 (aq) + 2HCl(aq) --- MgCl2 (aq) + 2H2O(l)

• chemistry -

mols HCl = M x L = ?
Convert mols HCl to mols Mg(OH)2 using the coefficients in the balanced equation.
Convert mols Mg(OH)2 to grams. g = mols x molar mass.

Got the first part. Thanks.
I'm still not sure how to convert mols using the balanced equation...
sorry, this class got hard really fast.
