To calculate the molar mass of AgNO3, we need to know the molar masses of the individual elements that make up this compound. The molar mass of an element is its atomic weight on the periodic table in g/mol. Step 1: Identify the Elements in the Compound AgNO3 is composed of Silver (Ag), Nitrogen (N), and Oxygen (O). Step 2: Find the Atomic Masses The atomic masses of these elements, usually found on the periodic table, are approximately: - Silver (Ag): 107.87 g/mol - Nitrogen (N): 14.01 g/mol - Oxygen (O): 16.00 g/mol Step 3: Determine the Number of Each Atom in the Compound In AgNO3, there is one atom of Silver (Ag), one atom of Nitrogen (N), and three atoms of Oxygen (O). Step 4: Calculate the Molar Mass Now, multiply the atomic mass of each element by the number of atoms of that element in the compound, and then add up all these masses. - Silver (Ag): 1 x 107.87 g/mol = 107.87 g/mol - Nitrogen (N): 1 x 14.01 g/mol = 14.01 g/mol - Oxygen (O): 3 x 16.00 g/mol = 48.00 g/mol Now, add these molar masses together: 107.87 g/mol (Ag) + 14.01 g/mol (N) + 48.00 g/mol (O) = 169.88 g/mol So, the molar mass of AgNO3 is approximately 169.88 g/mol.
