Let's calculate the molar mass of the compound \( \text{CrCl}_3 \cdot 2\text{H}_2\text{O} \).

1. **Chromium (Cr)**:
   - Atomic mass = 52.00 g/mol

2. **Chlorine (Cl)**:
   - Atomic mass = 35.45 g/mol
   - There are 3 chlorine atoms, so the total mass for chlorine = \( 3 \times 35.45 = 106.35 \, \text{g/mol} \).

3. **Water (H₂O)**:
   - Atomic mass of hydrogen (H) = 1.008 g/mol
   - Atomic mass of oxygen (O) = 16.00 g/mol
   - Molar mass of water = \( 2 \times 1.008 + 16.00 = 18.016 \, \text{g/mol} \)
   - There are 2 water molecules, so the total mass for water = \( 2 \times 18.016 = 36.032 \, \text{g/mol} \).

Now, we add these together:

\[
52.00 \, (\text{Cr}) + 106.35 \, (\text{Cl}_3) + 36.032 \, (\text{H}_2\text{O}) = 194.382 \, \text{g/mol}
\]

Thus, the molar mass of \( \text{CrCl}_3 \cdot 2\text{H}_2\text{O} \) is approximately **194.38 g/mol**.
