Number of moles of calcium ions present in 0.5 moles of Calcium carbonate are ( NA =Avagadro's number) - Sri Chaitanya Infinity Learn Best Online Courses for NCERT Solutions, CBSE, ICSE, JEE, NEET, Olympiad and Class 6 to 12

One mole of CaCO₃ contains….2 moles(2N_A) of ions…One mole(N_A) of Ca²⁺…One mole(N_A) of ${CO}_{3}^{2 -}$ ;

0.5 moles of CaCO₃ contains….1 mole(N_A) of ions…0.5 moles(0.5N_A) of Ca²⁺…0.5 moles(0.5N_A) of ${CO}_{3}^{2 -}$ ;

${CaCO}_{3} ⇌ {Ca}^{2 +} + {CO}_{3}^{2 -};$

Number of moles of calcium ions present in 0.5 moles of Calcium carbonate are ( $N_{A} = Avagadro' s number$ )
