Sagot :
The empirical formula of this compound is [tex]Fe_2O_3[/tex]
Empirical formula
To calculate the empirical formula of a compound, the value of moles of each element is needed.
As we have the information of the mass value, we will use the molar mass expression, which corresponds to:
[tex]MM_O = 16g/mol\\MM_Fe = 55.8g/mol[/tex]
[tex]MM = \frac{m}{mol}[/tex]
- O
[tex]16 = \frac{4.8}{x}[/tex]
[tex]x = 0.3mol[/tex]
- Fe
[tex]55.8=\frac{11.2}{x}\\x = 0.2[/tex]
As the value of the empirical formula must be an integer, simply multiply the two values by a common factor:
[tex]O = 0.3 \times 10 = 3\\Fe = 0.2 \times 10 = 2[/tex]
[tex]Fe_2O_3[/tex]
So, the empirical formula of this compound is [tex]Fe_2O_3[/tex].
