### Problem 5: Composition and Analysis of an Unknown Compound**An unknown compound is composed of carbon, fluorine, and boron. Details are provided below:**- **Carbon (C):** 42.23% by mass- **Boron (B):** 2.11% by mass**Tasks:**a) **Determine the Empirical Formula:** - Calculate the empirical formula of the compound. - Identify its molar mass.b) **Molar Mass Determination:** - A 2.251 g sample of the compound is dissolved in 347.0 mL of solution, resulting in a 0.01267 M solution. - Calculate the molar mass of the compound.c) **Determine the Molecular Formula:** - Use the information from parts (a) and (b) to find the molecular formula of the compound.**Guidelines:**1. **Convert Percent to Mass:** - Assume 100 g of the compound for simplicity, so the given percentages can be directly treated as masses in grams.2. **Convert Mass to Moles:** - Use atomic masses to convert the masses of each element to moles.3. **Divide by the Smallest Number of Moles:** - Divide each element's molar quantity by the smallest molar quantity among the elements.4. **Adjust to Whole Numbers:** - Multiply the resulting mole ratios by the smallest necessary factor to convert them to whole numbers, thereby determining the empirical formula.**Illustration on the Right:**- A simple flowchart in a rectangle is shown with steps: - Percent to Mass - Mass to Mole - Divide by Small - Multiply till wholeThis systematic approach provides a structured methodology for solving the problem and accurately determining the empirical and molecular formulas from the given data.
