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!
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.
