It's on chegg but I don't have a chegg membership

Do you have the balanced equation for this?

OpenStudy (vshiroky):

no

OpenStudy (nikato):

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?

OpenStudy (gebooors):

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
