Calculate molar concentration of formic acid solution if degree of dissociation is 4% K(HCOOH)=2.10^_4

The molar concentration of formic acid solution is 0.12 M

Explanation:

 cM                0             0

So dissociation constant will be:

Give c= ? and =

On solving for c we get:

Thus molar concentration of formic acid solution is 0.12 M

it's c (engineer's do their work with mechanical stuff not on any living being)
