What is the formula mass of PCl₃?

Question

Quizplus · Accepted Answer

The formula PCl₃ seems to be a typographical error, but interpreting it as PClS (Phosphorus, Chlorine, and Sulfur), the formula mass can be calculated as follows: Phosphorus (P) = 30.97 amu, Chlorine (Cl) = 35.45 amu, and Sulfur (S) = 32.06 amu. Adding these together gives 30.97 + 35.45 + 32.06 = 98.48 amu, which is not an option. However, assuming a mistake in interpreting the formula and considering the closest correct method for a plausible chemical compound, the calculation should involve the atomic masses of Phosphorus (P), Chlorine (Cl), and Sulfur (S) in a hypothetical correct formula. Without the exact masses of Uranium (U) and Boron (B) as implied in the question, and focusing on common elements, the closest match with provided options based on typical atomic masses would be for a different compound. Given the options, none directly match the calculation for PClS, suggesting a misunderstanding in the question's formula representation. Therefore, without a clear formula, the correct answer cannot be determined based on the provided formula, indicating a need for clarification.
