How many mL of stomach acid (assume it is .035 M HCI) can be neutralized by an antacid tablet containing .231g
Mg(OH)2 + 2HCl ==> 2H2O + MgCl2
Convert 0.231 g Mg(OH)2 to mols.
Convert mols Mg(OH)2 to mols HCl using the coefficients in the balanced equatin.
Convert mols HCl to liters HCl remembering that M = mols/L, then change to mL.
Post your work if you need more help.
