How many mL of stomach acid (assume it is .035 M HCI) can be neutralized by an antacid tablet containing .231g
Mg(OH)2?

  • chem -

    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.
