Question

A compound of coba, carbon, and oxygen contains 28.1% C and 34.5% CO. When 0.147 g of this compound is

dissolved in 6.72 g of cyclohexane, the solution freezes at 5.23°C. What is the molecular formula of this compound?

Freezing point(pure cyclohexane)=6.55 C

Kf (cyclohexane)= 20.0C/m

(Enter the elements in the order: CO, C, O)

Do not need to show work, thank you.
