Question

An acid of phosphorus has the following percentage composition phosphorus = 38.27% hydrogen = 2.47%  oxygen = 59.26 . Find the empirical formula of the acid and its molecular formula, given that its relative molecular mass is 162.


Solution

P = 38.2730.97=1.236
H = 2.471.00=2.47
O = 59.2616=3.704

Divide through by smallest value 
P = 1 
H= 2 
O = 3 

Empirical formula = H2PO3   

Formula mass = 2+31+48 = 81g/formula 

n=Molecular massempirical formula mass=16281=2

Molecular formula = (H2PO3)×2=H4P2O6   ​​​​​​​      ​​​​​​​
