Phosphorus trichloride, a chemical compound with the formula PCl3, possesses a molar mass of 137.33 g/mol. This value represents the mass of 6.022 x 10^23 molecules of PCl3, which consists of one phosphorus atom and three chlorine atoms. The molecular weight of PCl3 is the sum of the atomic masses of its constituent elements, which are 30.97 g/mol for phosphorus and 35.45 g/mol for chlorine. Understanding the molar mass of PCl3 is crucial for determining its concentration in solutions, calculating its reaction stoichiometry, and predicting its physical properties.

Unveiling the Chemical World: Phosphorus Trichloride, Molecular Weight, and Atomic Mass
In the vast and fascinating realm of chemistry, there are concepts that lay the foundation for our understanding of the universe around us. Let’s dive into three fundamental concepts that will make you a chemistry whiz!
1. Phosphorus Trichloride: The Mysterious PCl3
Imagine a compound that’s so reactive, it’s like the mischievous kid in the chemistry lab. That’s phosphorus trichloride (PCl3) for you! This colorless liquid has a chemical formula that reveals its composition: one phosphorus (P) atom and three chlorine (Cl) atoms. But don’t be fooled by its innocent appearance, PCl3 is a powerful chemical with some surprising properties.
2. Molecular Weight: Unraveling the Mass of Molecules
Every substance, from the air we breathe to the food we eat, has a molecular weight. It’s like a cosmic scale that tells us how heavy a molecule is. To calculate this weight, we simply add up the atomic masses of all the atoms in the molecule. For instance, the molecular weight of PCl3 is the sum of the atomic masses of one phosphorus atom and three chlorine atoms.
3. Atomic Mass: The Building Blocks of Weight
Before we dive into atomic mass, let’s make a distinction: molecular weight refers to the weight of molecules, while atomic mass refers to the weight of individual atoms. Atomic mass is measured in atomic mass units (amu) and is a fundamental property of each element. The periodic table, that colorful chart you’ve seen in science class, organizes elements based on their atomic masses, with phosphorus holding its place as the 15th element.
