Do you have the balanced equation for this?

vshiroky · Answer

no

nikato · Answer

ok. got it. there are actually two methods of doing this. do you want the fast, easy way, which is just plugging it into an equation, or dou u want to go long and use stoichiometry?

HF (aq) + NaOH (aq) -> NaF (aq) + H2O (l)

If we mark HF = 1 and NaOH = 2

Then V1 x c1 = V2 x c2

Now solve c1. in this case you can insert 
Volumes in millilitres, because
Units of volume cancel each other
