• # question_answer 33) How are 0.50 mol $N{{a}_{2}}C{{O}_{3}}$ and 0.50 M $N{{a}_{2}}C{{O}_{3}}$ different?

Molar mass of $N{{a}_{2}}C{{O}_{3}}=106\,gmo{{l}^{-1}}$ $\therefore$$0.5\,mol\,N{{a}_{2}}C{{O}_{3}}$ weighs 53 g. On the other hand, 0.5 $M\,\,N{{a}_{2}}C{{O}_{3}}$ means 0.5 moles of $N{{a}_{2}}C{{O}_{3}}$ is dissolved in one litre of solution.
