How Many Sodium Ions Are Contained in 99.6 mg of Na2SO3? The Molar Mass of Na2SO3 is 126.05 g/mol.

Solving the Problem: Calculating Sodium Ions in Na2SO3

When it comes to calculating the number of sodium ions contained in a given amount of Na2SO3, understanding the molar mass and molecular structure of the compound is crucial. In this article, we’ll explore how to calculate the number of sodium ions present in 99.6 mg of Na2SO3.

Understanding the Molar Mass of Na2SO3

Before diving into the calculation, let’s quickly review the molar mass of Na2SO3. The molar mass is the sum of the atomic weights of each element in a compound multiplied by their respective number of atoms. In the case of Na2SO3, the molar mass is 126.05 g/mol.

Calculating Sodium Ions: A Step-by-Step Approach

To calculate the number of sodium ions present in 99.6 mg of Na2SO3, we’ll follow these steps:

1. **Convert the given amount to moles**: Start by converting the given amount of Na2SO3 (99.6 mg) to moles. Since the molar mass is 126.05 g/mol, we can set up an equation:

moles = mass / molar mass
moles = 99.6 mg / 126.05 g/mol

After calculating, we get approximately 0.7933 mol.

2. **Determine the number of sodium ions per mole**: Now that we have the moles, let’s calculate the number of sodium ions (Na+) present in one mole of Na2SO3. Since the compound is composed of two sodium atoms and three sulfate ions (SO32-), we know there are two sodium ions for every molecule of Na2SO3.

The molecular formula for Na2SO3 is: 2Na+ + SO32-

Why Is This Calculation Important?

Calculating the number of sodium ions in a given amount of Na2SO3 is crucial in various industries, such as:

* **Agriculture**: Understanding the concentration of sodium ions in fertilizers can help farmers optimize crop growth and minimize environmental impact.
* **Pharmaceuticals**: Accurate calculation of sodium ions is essential in the development of medications that require precise dosing and formulation.

By knowing how many sodium ions are present in 99.6 mg of Na2SO3, you’ll be better equipped to tackle these challenges and make informed decisions in your respective field.
