Mass Percentage of Oxygen in C3H8O2
Mass percentage is a fundamental concept in chemistry, representing the relative amount of a specific element or compound within a substance. It plays a crucial role in various fields, including manufacturing, environmental science, and analytical chemistry.
In this article, we will explore the concept of mass percentage, particularly in the context of the compound C3H8O2, commonly known as propanol. We will delve into the formula and steps involved in calculating the mass percentage of oxygen in C3H8O2, its applications, and related concepts.
Calculating Mass Percentage of Oxygen
The mass percentage of an element in a compound is calculated using the following formula:
(Mass of Element / Molar Mass of Compound) x 100%
To calculate the mass percentage of oxygen in C3H8O2, we first need to determine its molar mass. The molar mass of a compound is the sum of the atomic masses of all its constituent atoms.
For C3H8O2, the molar mass is:
(12.01 g/mol) + 8(1.01 g/mol) + 2(16.00 g/mol) = 60.09 g/mol
Next, we need to find the mass of oxygen in C3H8O2. C3H8O2 contains two oxygen atoms, each with an atomic mass of 16.00 g/mol.
Therefore, the mass of oxygen in C3H8O2 is:
(16.00 g/mol) = 32.00 g/mol
Now we can plug these values into the mass percentage formula:
(32.00 g/mol / 60.09 g/mol) x 100% = 53.23%
Therefore, the mass percentage of oxygen in C3H8O2 is 53.23%.
Applications and Significance
