Question

Calculate the elemental composition (mole of the various elements) of the fuel, stating any assumptions you have to make to arrive at your answer.

Option 1: C: 1.0 mol, H: 2.0 mol, S: 0.005 mol, O: 2.3 mol
Option 2: C: 2.0 mol, H: 4.0 mol, S: 0.01 mol, O: 4.6 mol
Option 3: C: 3.0 mol, H: 6.0 mol, S: 0.015 mol, O: 6.9 mol
Option 4: C: 4.0 mol, H: 8.0 mol, S: 0.02 mol, O: 9.2 mol

Answer 1

To calculate the elemental composition of the fuel, we need to consider the moles of each element in the given options and find the most likely empirical formula based on the ratios.

Step-by-step explanation:

To calculate the elemental composition of the fuel, we need to consider the moles of each element in the given options. Assuming 1 mole of the compound in each option, we can calculate the mole ratio of each element. In Option 1, C: 1.0 mol, H: 2.0 mol, S: 0.005 mol, O: 2.3 mol. In Option 2, C: 2.0 mol, H: 4.0 mol, S: 0.01 mol, O: 4.6 mol. In Option 3, C: 3.0 mol, H: 6.0 mol, S: 0.015 mol, O: 6.9 mol. In Option 4, C: 4.0 mol, H: 8.0 mol, S: 0.02 mol, O: 9.2 mol. Based on these ratios, the most likely empirical formula for the fuel would be C3H8O.
