Question

An upside of iron contains 72.2% metal. Find the formula from the percentage

Answer 1

Answer:

• Start by converting the percent composition to grams by using a 100-g sample
• To find the mole ratio that exists between iron and oxygen, divide both values
• You can thus say that the empirical formula of the compound is.
