what is the relation of normality & molarity ? give me
formula?

Answer Posted / priyanka.r

molarity= wt/mol.wt* 1000/volume(ml)

normality= wt/equivalent wt*1000/volume(ml)

equivalent weight= molecular wt/acidity(or)basisity

example: HCL= MOLARITY&NORMALITY IS SAME
H2SO4= MOLARITY& NORMALITY WILL DIFFER BASED ON
THERE ASIDITY.
