Question

What are the empirical formulas for C9H20, P4O10, and B2H6?

Answer 1

1) C9H20 = NONANE

2) P4O10 = PHOSPHORUS PENTOXIDE

3) B2H6 = DIBORANE
emprical formula
C9H20 = C9H20
P4O10 = P2O5
B2H6 = BH3

Answer 2

Empirical formulas for $C_9H_2O$ ,  $P_4O_{10}$ and  $B_2H_6$ are $C_9H_2O$,  $P_2O_5$ and $BH_3$ respectively.

Explanation:

Molecular formula is the chemical formula which depicts the actual number of atoms of each element present in the compound.

Empirical formula is the simplest chemical formula which depicts the whole number of atoms of each element present in the compound.

1. For $C_9H_2O$ , the simplest whole number ratio will be 9: 2: 1 and thus empirical formula will be $C_9H_2O$.

2.  For $P_4O_{10}$ , the simplest whole number ratio will be 2: 5 and thus empirical formula will be $P_2O_5$.

3. For $B_2H_6$ , the simplest whole number ratio will be 1: 3 and thus empirical formula will be $BH_3$.
