come on, who would write that in standard form...
The oxidation number of P in Mg3P2 is 3. When writing ionic compounds, you swap the oxidation numbers and add them as the subscript.
Answer:
Empirical formula:
Fe₂O
Subscript of iron in empirical formula is 2.
Explanation:
Empirical formula:
It is the simplest formula that gives the smallest whole number ratio between the atoms of elements present in a compound.
Given data:
Mass of iron = 87.47 g
Mass of oxygen = 12.53 g
Empirical formula = ?
Solution:
Number of gram atoms of iron = 87.47 /55.845 =1.57 grams atoms
Number of gram atoms of oxygen = 12.53 / 16 = 0.78 grams atoms
Atomic ratio:
Fe : O
1.57/0.78 : 0.78/0.78
2 : 1
Fe : O = 2 : 1
Empirical formula:
Fe₂O
Subscript of iron in empirical formula is 2.
