Calculating the Molar Mass of AgNO3: A Step-by-Step Guide

Now that we have a solid understanding of molar mass and the significance of silver nitrate, let's proceed with calculating the molar mass of AgNO3. Here's a step-by-step guide:

Step 1: Identify the Elements and Their Atomic Masses

The chemical formula of silver nitrate is AgNO3, which indicates that it consists of the following elements:

• Silver (Ag)
• Nitrogen (N)
• Oxygen (O)

To calculate the molar mass, we need to know the atomic masses of these elements. You can find these values on the periodic table:

• Atomic mass of Ag (Silver) = 107.87 g/mol
• Atomic mass of N (Nitrogen) = 14.01 g/mol
• Atomic mass of O (Oxygen) = 16.00 g/mol

Step 2: Determine the Number of Atoms of Each Element

Next, we need to determine the number of atoms of each element present in one molecule of AgNO3. From the chemical formula, we can see that:

• There is 1 atom of Silver (Ag)
• There is 1 atom of Nitrogen (N)
• There are 3 atoms of Oxygen (O)

Step 3: Multiply the Atomic Mass of Each Element by the Number of Atoms

Now, we multiply the atomic mass of each element by the number of atoms of that element in the compound:

• Mass of Ag in AgNO3 = (1 atom Ag) x (107.87 g/mol) = 107.87 g/mol
• Mass of N in AgNO3 = (1 atom N) x (14.01 g/mol) = 14.01 g/mol
• Mass of O in AgNO3 = (3 atoms O) x (16.00 g/mol) = 48.00 g/mol

Step 4: Sum the Masses of All the Elements

Finally, we add up the masses of all the elements to obtain the molar mass of AgNO3:

Molar mass of AgNO3 = (Mass of Ag) + (Mass of N) + (Mass of O) = 107.Still, 01 g/mol + 48. Practically speaking, 87 g/mol + 14. 00 g/mol = 169.
