Answer:

The molecular formula would be C11H11

Step-by-step explanation:

To find the molecular formula, we need to determine the molecular mass of the compound. The empirical formula CH has a molar mass of 13.01 g/mol (C) + 1.01 g/mol (H) = 14.02 g/mol.

To calculate the molecular formula, we divide the molar mass of the compound (156.21 g/mol) by the molar mass of the empirical formula (14.02 g/mol).

156.21 g/mol / 14.02 g/mol = 11.14

This means that the molecular formula is approximately 11 times the empirical formula, so the molecular formula would be C11H11.

(hope that helps)
