$C_{9} H_{20}$ $C_9H_20$ , $P_{2} O_{5}$ $P_2O_5$ and $B H_{3}$ $BH_3$ .

Explanation:

To find the empirical formula from a molecular formula, you should divide the subscripts by the same integer in order to get the smallest whole numbers.

The empirical formula of $C_{9} H_{20}$ $C_9H_20$ is $C_{9} H_{20}$ $C_9H_20$ itself since there is no integer that we can find to divide $9$ $9$ and $20$ $20$ to get smaller whole numbers.

The empirical formula of $P_{4} O_{10}$ $P_4O_10$ is $P_{2} O_{5}$ $P_2O_5$ . We get it by dividing both subscripts by $2$ $2$ .

The empirical formula of $B_{2} H_{6}$ $B_2H_6$ is $B H_{3}$ $BH_3$ . We get it by dividing both subscripts by $2$ $2$ .
