Hexane has a chemical formula of $C_{6} H_{14}$ $C_6H_14$ . This would make the the empirical formula for hexane $C_{3} H_{7}$ $C_3H_7$

For the Hydrocarbons that end in the suffix -ane like butane, propane and hexane, the base formula is $C_{n} H_{2 n + 2}$ $C_nH_(2n+2)$ .

Propane is for the prefix pro- n = 3
$C_{3} H_{(2) 3 + 2}$ $C_3H_((2)3+2)$ so the formula is $C_{3} H_{8}$ $C_3H_8$
Empirical Formula would be $C_{3} H_{8}$ $C_3H_8$

Butane is for the prefix but- n = 4
$C_{4} H_{(2) 4 + 2}$ $C_4H_((2)4+2)$ so the formula is $C_{4} H_{10}$ $C_4H_10$
Empirical Formula would be $C_{2} H_{5}$ $C_2H_5$

Octane is for the prefix Oct- n = 8
$C_{8} H_{(2) 8 + 2}$ $C_8H_((2)8+2)$ so the formula is $C_{8} H_{18}$ $C_8H_18$
Empirical Formula would be $C_{4} H_{9}$ $C_4H_9$

I hope this was helpful.
