Final answer:
The molecular formula of a compound with an empirical formula of CH2O and a molar mass of 150 g/mol is C5H10O5.
Step-by-step explanation:
The question asks for the molecular formula of a compound with an empirical formula of CH2O and a molar mass of 150 g/mol. To find the molecular formula, we must first determine the molar mass of the empirical formula CH2O which is 12.01 (C) + 2(1.008) (H) + 16.00 (O) = 30.026 g/mol. Dividing the given molar mass of the compound (150 g/mol) by the molar mass of the empirical formula (30.026 g/mol) gives us a factor of approximately 5. Therefore, the molecular formula is the empirical formula multiplied by this factor, resulting in C5H10O5. Hence, option a) C5H10O5 is the correct answer.
