Click For Summary
To calculate the number of moles of ions in 0.0200g of AgNO3, first determine the molar mass of AgNO3, which is approximately 169.87 g/mol. Using the formula moles = mass (g) / molar mass (g/mol), divide 0.0200g by 169.87 g/mol to find the moles of AgNO3. Since each formula unit of AgNO3 dissociates into three ions (one Ag+ and two NO3-), multiply the moles of AgNO3 by three to find the total moles of ions. This results in approximately 0.000353 moles of ions in 0.0200g of AgNO3. Understanding this calculation is essential for solving similar chemistry problems.
