To determine the molecular formula of the compound given its molecular weight and empirical formula, we need to follow these steps:
1. Determine the molecular weight of the empirical formula:
- The empirical formula is [tex]\(C_3H_8O\)[/tex].
- The atomic weight of Carbon (C) is 12.01.
- The atomic weight of Hydrogen (H) is 1.01.
- The atomic weight of Oxygen (O) is 16.00.
- Calculate the weight of the empirical formula:
[tex]\[
(3 \times 12.01) + (8 \times 1.01) + (1 \times 16.00) = 60.11
\][/tex]
2. Compare the molecular weight of the compound to the weight of the empirical formula:
- The given molecular weight is 60.10.
- Calculate the ratio of the molecular weight to the empirical formula weight:
[tex]\[
\frac{60.10}{60.11} \approx 1
\][/tex]
3. Determine the molecular formula:
- The ratio is approximately 1, meaning the molecular formula and the empirical formula are the same.
- Hence, the molecular formula is [tex]\(C_3H_8O\)[/tex].
So, the molecular formula of the compound is:
[tex]\[ C_3H_8O \][/tex]
You should select from the drop-down menu:
