Chemistry
Any one have any ideas?
Struggling with how to do the following
Calculate the pH of a 0.10 mol dm-3 solution ethanoic acid which has dissociation constant Ka of 1.8 x 10-5 mol dm-3.
I think I know the second part just not what to do with 0.10 mol dm-3. any advice welcome

[H+]=square root of (ka x [acid])
then -log[H+]=pH
so the answer should be 2.9
