How many individual hydroxide ions (OH)- are found in 13.4mL of 0.586M Ba(OH)2?

I'm not quite sure how to do this. Thank you!

  • Chemistry -

    How many moles Ba(OH)2 do you have?
    moles = M x L.
    There will be twice the molar concn of OH^- because there are two OH ions/1 molecule Ba(OH)2.
    There are 6.022 x 10^23 OH^- in a mole of them. How many in the number of moles you have? Go from there.
