Introduction
Calculating the molecular formula of a compound based on percentages is a crucial task in chemistry. To simplify this process, we present a user-friendly Molecular Formula Calculator with Percentages. This article will guide you through its usage, the underlying formula, an example solve, frequently asked questions, and a conclusion.
How to Use
- Input the percentages of each element in the compound.
- Click the “Calculate” button.
- Instantly obtain the molecular formula of the compound.
Formula
The calculation is based on the following formula:
Number of atoms of each element=(Percentage of the element100)×Multiplier
Where the multiplier is the smallest whole number that makes all the atom counts integers.
Example
Suppose you have a compound with 40% carbon, 6.67% hydrogen, and 53.33% oxygen.
Carbon atoms=(40100)×Multiplier Hydrogen atoms=(6.67100)×Multiplier Oxygen atoms=(53.33100)×Multiplier
By solving this system of equations, you’ll find the values for the atoms of each element, and the molecular formula can be determined.
