How many grams of H2SO4 will be needed to react with 69.3gof NaOH? Can you list steps so I can understand this? Thanks

  • Chemistry -

    Write and balance the equation.
    2NaOH + H2SO4 ==> Na2SO4 + 2H2O

    How many mols of NaOH do you have? That's mol = grams/molar mass = 69.3/40 = about 1.73

    From the equation, use the coefficients to convert mols NaOH to mols H2SO4. That's 1.73 mol NaOH x (1 mol H2SO4/2 mol NaOH) = 1.73/2 = about 0.8 or so.

    Now mols H2SO4 converted to grams.
    mol = grams/molar mass. You have mols and molar mass, solve for grams.
