The Average Atomic Mass of Element B: A Step-by-Step Calculation
In chemistry, the average atomic mass of an element is a crucial concept that helps us understand the properties and behavior of that element. It is calculated by taking into account the atomic masses of the different isotopes of the element and their relative abundances. In this article, we will guide you through the process of calculating the average atomic mass of element B using the data provided in the table below.
The table below provides the data needed to calculate the average atomic mass of element B.
| Isotope | Atomic mass (amu) | Relative abundance (%) |
|---|---|---|
| B-10 | 10.01 | 19.9 |
| B-11 | 11.01 | 80.1 |
To calculate the average atomic mass of element B, we need to multiply the atomic mass of each isotope by its relative abundance, expressed as a decimal. We then add up these products to get the average atomic mass.
Step 1: Convert Relative Abundance to Decimal
First, we need to convert the relative abundance of each isotope from percentage to decimal. We do this by dividing the percentage by 100.
| Isotope | Atomic mass (amu) | Relative abundance (decimal) |
|---|---|---|
| B-10 | 10.01 | 0.199 |
| B-11 | 11.01 | 0.801 |
Step 2: Multiply Atomic Mass by Relative Abundance
Next, we multiply the atomic mass of each isotope by its relative abundance.
| Isotope | Atomic mass (amu) | Relative abundance (decimal) | Product |
|---|---|---|---|
| B-10 | 10.01 | 0.199 | 1.998 |
| B-11 | 11.01 | 0.801 | 8.821 |
Step 3: Add Up the Products
Finally, we add up the products to get the average atomic mass of element B.
Average atomic mass = 1.998 + 8.821 = 10.819
In this article, we have walked you through the process of calculating the average atomic mass of element B using the data provided in the table. We have shown you how to convert relative abundance from percentage to decimal, multiply atomic mass by relative abundance, and add up the products to get the average atomic mass. By following these steps, you can calculate the average atomic mass of any element using the data provided.
The average atomic mass of an element is an important concept in chemistry because it helps us understand the properties and behavior of that element. It is used to determine the atomic mass of an element, which is a fundamental property of that element. The average atomic mass is also used to calculate the atomic mass of compounds and mixtures.
The average atomic mass of an element has many real-world applications. For example, it is used in the production of nuclear power plants, where the average atomic mass of uranium is used to determine the energy output of the plant. It is also used in the production of medical isotopes, where the average atomic mass of certain isotopes is used to determine their half-life and decay rate.
In conclusion, the average atomic mass of element B is an important concept in chemistry that helps us understand the properties and behavior of that element. By following the steps outlined in this article, you can calculate the average atomic mass of any element using the data provided. The average atomic mass has many real-world applications, including the production of nuclear power plants and medical isotopes.
