**Combustion Analysis of a Hydrocarbon**When 1.699 grams of a hydrocarbon, \( C_xH_y \), were burned in a combustion analysis apparatus, 5.598 grams of \( CO_2 \) and 1.528 grams of \( H_2O \) were produced.In a separate experiment, the molar mass of the compound was found to be 40.06 g/mol. Determine the empirical formula and the molecular formula of the hydrocarbon.**Diagram Explanation**The image shows a combustion analysis apparatus. A sample is placed in a combustion chamber where it reacts with oxygen (\( O_2 \)). The products of the combustion pass through two absorbers: one for water (\( H_2O \)) and another for carbon dioxide (\( CO_2 \)).**Calculation Section**Enter the elements in the order presented in the question.- Empirical formula: [ ]- Molecular formula: [ ]

A student performed a similar experiment to the one you performed: They took a crucible and lid, cleaned them, heated them over a flame, and after cooling found their combined mass to be 22.538 g. The student then added a sample of zinc(II) sulfate hydrate (ZnSO4·“n”H2O) to the crucible so the combined mass of the sample, crucible, and lid was 25.896 g. They heated this sample for 10 minutes with the lid ajar, let it cool, and measured the mass of the crucible, sample, and lid to be 25.054 g. a. Based on this experiment, what is the formula for they hydrated zinc(II) sulfate compound? b. The student later looked on the reagent bottle for zinc(II) sulfate hydrate and found the actual formula was ZnSO4·7H2O. If everything had been done correctly, what value should the student have expected for the final mass of their sample, crucible, and lid after heating?
