Calculating the molar mass of a compound like C₂F₃Cl₃ is a fundamental skill in chemistry. Whether you’re a student, researcher, or professional, understanding how to determine molar mass is crucial for various applications, from laboratory experiments to industrial processes. In this guide, we’ll walk you through the C₂F₃Cl₃ molar mass calculation step-by-step, ensuring you grasp the concept effortlessly.
What is Molar Mass?
Molar mass is the mass of one mole of a substance, expressed in grams per mole (g/mol). It’s calculated by summing the atomic masses of all atoms in a molecule. For C₂F₃Cl₃, we’ll need the atomic masses of carbon ©, fluorine (F), and chlorine (Cl).
Step-by-Step Guide to Calculate C₂F₃Cl₃ Molar Mass
1. Identify Atomic Masses
First, refer to the periodic table for the atomic masses:
- Carbon ©: 12.01 g/mol
- Fluorine (F): 19.00 g/mol
- Chlorine (Cl): 35.45 g/mol
📌 Note: Ensure you use the most accurate atomic masses for precise calculations.
2. Multiply Atomic Masses by Their Respective Atoms
Next, multiply the atomic mass of each element by the number of atoms in the molecule:
- Carbon: 2 × 12.01 = 24.02 g/mol
- Fluorine: 3 × 19.00 = 57.00 g/mol
- Chlorine: 3 × 35.45 = 106.35 g/mol
3. Sum the Values
Add the calculated masses to find the total molar mass:
24.02 + 57.00 + 106.35 = 187.37 g/mol
| Element | Atomic Mass (g/mol) | Number of Atoms | Total Mass (g/mol) |
|---|---|---|---|
| Carbon (C) | 12.01 | 2 | 24.02 |
| Fluorine (F) | 19.00 | 3 | 57.00 |
| Chlorine (Cl) | 35.45 | 3 | 106.35 |
| Total Molar Mass | 187.37 | ||
