Calculate the H3O concentration if 100.0 ml of the .10M HNO3 solution is diluted to 1.0L with water?
0.10M HNO3 x (100/1000) = ?
0.01M? Is is really that simple, or did I mess up?
It really is that simple. I prefer to use the dilution formula as
c1v1 = c2v2 where
c = concn
v = volume
and that works when volume is other than mL (as long as the units for v1 and v2 are the same) and c1 and c2 can be concentrations other than molarity.
