To calculate the total mass of the reactants in a chemical reaction, you need to know the reactants and their chemical formulas. Although you haven't provided the specific reaction equation or the relevant atomic masses for iron chloride (FeCl₃) and water (H₂O), I can guide you on how to calculate this if you supply the atomic masses.
1. **Identify the reactants and their formulas**:
Commonly, the reaction between iron chloride (FeCl₃) and water (H₂O) could look something like this:
\[
\text{FeCl}_3 + \text{H}_2\text{O} \rightarrow \text{Products}
\]
2. **Calculate the molar mass of each reactant**:
- For iron chloride (FeCl₃), the molar mass:
- Fe: 55.85 amu (approximate value)
- Cl: 35.45 amu (since there are 3 Cl atoms, multiply by 3)
- Total for FeCl₃:
\[
55.85 + (3 \times 35.45) = 55.85 + 106.35 = 162.20 \text{ amu}
\]
- For water (H₂O), the molar mass:
- H: 1.01 amu (approximately, for 2 H atoms)
- O: 16.00 amu
- Total for H₂O:
\[
(2 \times 1.01) + 16.00 = 2.02 + 16.00 = 18.02 \text{ amu}
\]
3. **Add the atomic masses of the reactants**:
- Total mass of the reactants:
\[
162.20 \text{ amu} + 18.02 \text{ amu} = 180.22 \text{ amu}
\]
4. **Sum up the total mass and check options**:
If you've provided the options, please double-check if none of these match the calculated value or provide the atomic masses you are using for clarity.
From the options you provided (215 amu, 161 amu, 108 amu, 179 amu), based on typical calculations you may need to confirm the exact atomic masses or adjust based on your context.
If you have specific atomic masses or a different reaction, please share those details for a more accurate calculation.
