Answer:
Explanation:
<u>1. Calculate the mass of C in 1.24 g of CO₂</u>
<u>2. Calculate the mass of H in 0.255g of H₂O</u>
<u />
<u>3. Calculate the mass of O by difference</u>
<u>4. Convert every mass to number of moles:</u>
- C: 0.3384g / (12.011g/mol) = 0.02817 mol
- H: 0.02854g / (1.008g/mol) = 0.02831 mol
- O: 0.15206g / (15.999g/mol) = 0.009504 mol
<u />
<u>5. Divide every number of moles by the least number of moles (0.009504):</u>
- C: 0.02817/0.009504 = 2.96 ≈ 3
- H: 0.02831 / 0.009504 ≈ 3
- O: 0.009504 / 0.009504 = 1
<u>6. Those numbers are the respective subscripts in the empirical formula:</u>
<span>After many experiments and many different approaches to the question, the scientist may be able to develop a theory. The theory explains why nature behaves in the way described by the natural law. It answers not only the original question, but also any other questions that were raised during the process. The theory also predicts the results of further experiments, which is how it is checked. Theories are not the end of the process.</span>
