1. Calculate for your percent error for each trial. Use the Daum Equation Editor to create your equations and add it to your Padlet or Mural report.

A: #1 1.84 grams- 2.5grams (divided) 1.84 grams X 100 = -35.87%

#2 1.47grams - 1.44 grams (divide) 1.47 grams X 100 = 2.04%

#3 1.89grams -2.08 grams(divide) 1.89gramsX 100 = -10.05%

2. If your percent error was positive, what logical sources of error might have been the cause? Explain. Answer this question regardless of what your results were.

A: A logical source of error that could cause our percent error to be positive is that we didn't measure our accepted correctly or some of the salt that spilled.

3. If your percent error was negative, what logical sources of error might have been the cause? Explain. Answer this question regardless of what your results were.

A: A logical source of error that could have caused our percent to be negative is because we might have not let the water fully evaporate or some salt was still in the beaker before

4. Which ESLR or ESLR’s were  addressed in the activity? State the ESLR and explain why in a short paragraph.
