The empirical formula : C₁₂H₁₇N₂O₄P
The empirical formula is the smallest comparison of atoms of compound =mole ratio of the components
The principle of determining empirical formula
[tex]\tt \dfrac{50.7}{12}=4.225[/tex]
[tex]\tt \dfrac{6.03}{1}=6.03[/tex]
[tex]\tt \dfrac{9.86}{14}=0.704[/tex]
[tex]\tt \dfrac{22.51}{16}=1.407[/tex]
[tex]\tt \dfrac{10.9}{31}=0.352[/tex]
Divide by the smallest mole ratio(0.352)
C : H : N : O : P
[tex]\tt C\rightarrow \dfrac{4.225}{0.352}=12[/tex]
[tex]\tt H\rightarrow \dfrac{6.03}{0.352}=17[/tex]
[tex]\tt N\rightarrow \dfrac{0.704}{0.352}=2[/tex]
[tex]\tt O\rightarrow \dfrac{1.407}{0.352}=4[/tex]
[tex]\tt P\rightarrow \dfrac{0.352}{0.352}=1[/tex]
