1 mole of Magnesium chloride gives 1 mole of magnesium ion and 2 mole of chloride ions.
In magnesium chloride,
Number of moles of magnesium ion = 1/2 x number of Chloride ions
Number of moles of magnesium ion = 1/2 x 0.6 = 0.3 moles
1 mole of Magnesium sulphate gives 1 mole of magnesium ion and 1 mole of sulphate ions.
In magnesium sulphate,
Number of moles of magnesium ion = number of sulphate ions
Number of moles of magnesium ion = 0.2 moles
Total number of moles of magnesium ions in the mixture of magnesium chloride and magnesium sulphate = 0.3+0.2 =0.5 moles
1 mole of Magnesium chloride gives 1 mole of magnesium ion and 2 mole of chloride ions.
