Answer:
72.03 %
Explanation:
Total mass of dolomite = 9.66 g
Let the mass of Magnesium carbonate = x g
The mass of calcium carbonate = 9.66 - x g
Calculation of the moles of Magnesium carbonate as:-
Molar mass of Magnesium carbonate = 122.44 g/mol
The formula for the calculation of moles is shown below:
Thus,
Calculation of the moles of calcium carbonate as:-
Molar mass of calcium carbonate = 100.0869 g/mol
Thus,
According to the reaction shown below:-
In both the cases, the oxides formed from the carbonates in the 1:1 ratio.
So, Moles of MgO =
Molar mass of MgO = 40.3044 g/mol
Thus, Mass = Moles*Molar mass =
Moles of CaO =
Molar mass of CaO = 56.0774 g/mol
Thus, Mass = Moles*Molar mass =
Given that total mass of the oxide = 4.84 g
Thus,
Thus, the mass of Magnesium carbonate = 6.9582 g
