Question

Determina la formula molecular de un compuesto cuya forma empírica es P2 O5 y su masa molecular es de 284 g/mol.

Answer 1

FE: P2O5

P: 2 x 30.9 = 61.8 g/mol
O. 5 x 16 = 80 g/mol
````````````````````````````````
           Mm = 141.8 g/mol

n= 284 g/mol
     ``````````````
     141.8 g/mol

n = 2

FM: (P2O5)2 =  P4O10
