Phase 1: Data comprehension.
The objective is to determine the molecular weight of calcium carbonate, \( \text{CaCO}_3 \).
Phase 2: Calculation of \( \text{CaCO}_3 \) molar mass.
The molecular weight of \( \text{CaCO}_3 \) is obtained by aggregating the atomic masses of all constituent atoms.
* Calcium (Ca) possesses an atomic mass of \( 40.1 \, \text{g/mol} \).
* Carbon (C) has an atomic mass of \( 12.0 \, \text{g/mol} \).
* Oxygen (O) has an atomic mass of \( 16.0 \, \text{g/mol} \). The formula \( \text{CaCO}_3 \) contains three oxygen atoms.
Consequently, the molecular weight is calculated as follows:
\[
\text{Molar mass of CaCO}_3 = 40.1 + 12.0 + (3 \times 16.0) = 40.1 + 12.0 + 48.0 = 100.1 \, \text{g/mol}
\]
Conclusion: The molecular weight of \( \text{CaCO}_3 \) is approximately \( 100 \, \text{g/mol} \).
