When reacting 100 mL of 2 M HCl with 100 mL of 2 M NaOH,
how many milliliters of water should be produced?
(REM: Density of Water)

  • chemistry -

    HCl + NaOH ==> NaCl + H2O
    moles HCl = M x L = ??
    moles NaOH = M x L = same number.
    moles H2O produced = same number.
    grams H2O = moles x molar mass.
    Look up density of water at the temperature of the reaction and mass = volume x density. You know mass and density, solve for volume. You don't list a T; therefore, I assume the problem expects you to assume density H2O = 1.00 g/mL.
