1. The empirical formula of the compound is CaH₂C₂O₆
2. The name of the compound is Calcium hydrogen carbonate
From the question given above, the following data were obtained:
Calcium (Ca) = 24.7%
Hydrogen (H) = 1.2%
Carbon (C) = 14.8%
Oxygen (O) = 59.3%
1. Determination of the empirical formula of the compound.
Divide by their molar mass
Ca = 24.7 / 40 = 0.6175
H = 1.2 / 1 = 1.2
C = 14.8 / 12 = 1.233
O = 59.3 / 16 = 3.706
Divide by the smallest
Ca = 0.6175 / 0.6175 = 1
H = 1.2 / 0.6175 = 2
C = 1.233 / 0.6175 = 2
O = 3.706 / 0.6175 = 6
Thus, the empirical formula of the compound is CaH₂C₂O₆
2. Naming of the compound.
To name the compound, we shall rearrange the empirical formula of the compound. This is given below:
Empirical formula => CaH₂C₂O₆
Empirical formula => Ca(HCO₃)₂
Name the compound => Calcium hydrogen carbonate
