Final answer:
The molecular formula for hexane, an alkane with six carbons, is C6H14, adhering to the general alkane formula CnH2n+2.
Step-by-step explanation:
The molecular formula of hexane, the alkane with six carbons, is C6H14. This is derived from the general formula for alkanes, which is CnH2n+2. Applying this formula to hexane:
C6H(2 x 6) + 2 = C6H14.
This indicates that hexane has six carbon atoms (C) and fourteen hydrogen atoms (H).
