A 3.26g sample of metallic sodium is added to 200mL of water. How many moles of NaOH are produced?

  • Chemistry -

    The chemical equation is:
    2Na(s) + 2H2O --> 2NaOH + H2
    Divide the grams of Na by the atomic mass of Na to get the moles of Na. The number of moles of NaOH are equal to the number of moles of Na.
