Concentration of Silver Nitrate Solution Calculation

What is the percentage by mass concentration of a solution containing 12 grams of silver nitrate (AgNO3) dissolved in 210 grams of water?

The percentage by mass concentration of the solution is 5.71%.

To calculate the percentage by mass concentration (%m/m) of a solution, we use the formula:

%m/m = (mass of solute / mass of solution) * 100%

In this case, the mass of the solute (AgNO3) is 12 grams and the mass of the solution is 210 grams. Plugging these values into the formula:

%m/m = (12 / 210) * 100%

%m/m = 0.057 * 100%

%m/m = 5.71%

Therefore, the concentration of the silver nitrate solution is 5.71% by mass.
