A _______ formula represents a whole number ratio to the simplest form...
Empirical Formula Explanation:
Empirical formula is the simplest form of a chemical formula that shows the ratio of elements present in a compound. It represents the whole number ratio of atoms of each element in a compound.
Importance of Empirical Formula:
- It helps in determining the basic building blocks of a compound.
- It provides information about the relative proportions of different elements in a compound.
- It allows chemists to compare different compounds and understand their compositions.
Calculation of Empirical Formula:
To calculate the empirical formula of a compound, one needs to know the mass of each element present in the compound. This can be done by converting the mass of each element to moles and then finding the simplest whole number ratio of moles of each element.
Example:
For example, if a compound contains 40% carbon, 6.67% hydrogen, and 53.33% oxygen by mass, the empirical formula can be calculated by assuming a 100g sample. This would give 3.33 moles of carbon, 6.67 moles of hydrogen, and 3.33 moles of oxygen. Dividing each by the smallest number of moles gives a ratio of 1:2:1, resulting in the empirical formula CH2O for the compound.
Therefore, the empirical formula represents a whole number ratio to the simplest form of a compound's composition.
