Question

3. 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?

Answer 1

To be sure of the value you will obtain

Answer 2

To be sure of the value you will obtain

Step-by-step explanation:

Trial 1

Mass of calorimeter: 409g

Temp of calorimeter: 20Cº

Mass of calorimeter + water: 457g

Temp of calorimeter + water: 20Cº

Mass of calorimeter + water + ice: 510g

Temp of calorimeter + water + ice: –

Mass of calorimeter + ice: 450g

Temp of calorimeter + ice: 0Cº

Trial 2

Mass of calorimeter: 409g

Temp of calorimeter: 20Cº

Mass of calorimeter + water: 461g

Temp of calorimeter + water: 22Cº

Mass of calorimeter + water + ice: 515g

Temp of calorimeter + water + ice: –

Mass of calorimeter + ice: 447g

Temp of calorimeter + ice: 0Cº

Trial 3

Mass of calorimeter: 409g

Temp of calorimeter: 20Cº

Mass of calorimeter + water: 459g

Temp of calorimeter + water: 22Cº

Mass of calorimeter + water + ice: 513g

Temp of calorimeter + water + ice: –

Mass of calorimeter + ice: 448g

Temp of calorimeter + ice: 0Cº
