What was your average percent error for all three trials? in this experiment you did three trials. why was it suggested that you do three trials and not fewer? here's all the info i got: ! the first: empty mass of caloriometer: 409g mass of caloriometer + water : 454 mass of water: 45 starting temp: 22c mass of cal. + water + ice : 503 final temp: 0 c cal + unmelted ice: 444 total of ice at the beginning: 49 total ice unmelted: 35 total ice melted: 14 the second: empty mass of caloriometer: 409g mass of caloriometer + water : 458 mass of water: 49 starting temp: 20 mass of cal. + water + ice : 503 final temp: 0 c cal + unmelted ice: 441 total of ice at the beginning: 45 total ice unmelted: 32 total ice melted: 13 the third: empty mass of caloriometer: 409g mass of caloriometer + water : 463 mass of water: 54 starting temp: 20 mass of cal. + water + ice : 516 final temp: 0 c cal + unmelted ice: 448 total of ice at the beginning: 53 total ice unmelted: 39 total ice melted: 14
