In volumetric analysis, how does one convert concentration from g/dm3 to mol/dm3?

gdm^-3/gmol^-1

g/g=1  dm^-3/1=dm^3    1/mol^-1=mol^1      1 x dm^-3 x mol^1     mol/dm^3

To convert from g/dm^3 to mol/dm^3 you have to divide g/dm^3 by g/mol or the molecular mass.

i'm not sure

explanation:

i'll try whatever you got

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.
