Writing аnd Reаding Chemicаl Fоrmulas: Identifying the Unknоwn Pоwder (Based on Chapter 2, Section 2.4 — "Chemical Formulas") The medical laboratory is still working to identify the unknown white crystalline powder. Three candidate compounds are being considered: sodium chloride — NaCl calcium carbonate — CaCO₃ glucose — C₆H₁₂O₆ A. For each of the three compounds, list each element present and state how many atoms of that element are in one formula unit or molecule. Example: H₂O contains 2 hydrogen atoms and 1 oxygen atom. (Help: Section 2.4 — molecular formulas and subscripts) B. Glucose has the molecular formula C₆H₁₂O₆. Write its empirical formula, and in 1–2 sentences explain the difference between what a molecular formula and an empirical formula tell you. (Help: Section 2.4 — empirical formulas and Example 2.6) C. The mass spectrometer detects a gas released by the sample. The gas contains 1 carbon atom and 2 oxygen atoms per molecule. Write its chemical formula, and explain how the subscripts show the ratio of carbon to oxygen atoms. (Help: Section 2.4)
