To find the percent by mass of silver nitrate in the solution, we'll use the formula:Percent by mass = (mass of solute / total mass) × 100Given:- Mass of silver nitrate (solute) = 10 grams- Mass of water = 750 gramsFirst, calculate the total mass:Total mass = mass of silver nitrate + mass of waterTotal mass = 10 grams + 750 gramsTotal mass = 760 gramsNow, calculate the percent by mass:Percent by mass = (10 grams / 760 grams) × 100Percent by mass ≈ 1.32%Therefore, the percent by mass of the solution is approximately 1.32% ¹.
