Answer

Explanation:

Step1: Calculate empirical - formula weight

The atomic weights of C = 12.01, H = 1.008, O = 16.00. For the empirical formula (C_3H_8O), the empirical - formula weight (M_{empirical}=(3\times12.01)+(8\times1.008)+16.00) [M_{empirical}=36.03 + 8.064+16.00=60.094\approx60.10]

Step2: Determine the multiple (n)

The multiple (n=\frac{M_{molecular}}{M_{empirical}}). Since (M_{molecular} = 60.10) and (M_{empirical}\approx60.10), (n = 1)

Step3: Find the molecular formula

Since (n = 1), the molecular formula is the same as the empirical formula, which is (C_3H_8O)

Answer:

C: 3, H: 8, O: 1
