**Name:___________________ Class:___________________ Date:___________________**## Writing Empirical Formulas from Chemical FormulasFor questions #1–15, write the empirical formula for each chemical formula. Then, calculate the empirical formula mass for the chemical formulas in questions 16–21. Use the space below each question for your calculations. ### Empirical Formula Mass Calculation Exercise#### Instructions:For each of the following empirical formulas, calculate the empirical formula mass. This information is essential for understanding and determining molecular formulas from empirical data.---**16. Empirical Formula: CH**- **Empirical Formula Mass:**---**17. Empirical Formula: CH₂O**- **Empirical Formula Mass:**---**18. Empirical Formula: C₄H₅N₂O**- **Empirical Formula Mass:**---**19. Empirical Formula: HgF**- **Empirical Formula Mass:**---**20. Empirical Formula: C₄H₆O**- **Empirical Formula Mass:**---**21. Empirical Formula: C₆H₁₂O₅**- **Empirical Formula Mass:**---#### Notes on Calculation:To find the empirical formula mass:1. **Identify the atomic masses** of each element present in the formula (you can refer to the periodic table).2. **Multiply** the atomic mass of each element by the number of atoms of that element in the empirical formula.3. **Sum up** these values to get the empirical formula mass.For example, for **CH** (Cerium Hydride):- Carbon (C): Atomic mass ≈ 12 amu- Hydrogen (H): Atomic mass ≈ 1 amu - Empirical formula mass = (1 × 12) + (1 × 1) = 12 + 1 = 13 amuPlease complete the provided empirical formulas with the calculated masses to enhance your understanding of empirical formulas and their significance in chemistry.
