Percent Error
Problem #1: What is the percent error in determining the volume of a lare graduated cylinder in a cm^3?
Problem #2: What is the percent error in determining the mass of 1 mL of water in grams?
Procedure 1:
1) Measure height of cylinder to the 250mL mark in cm
2) Measure diameter of cylinder in cm
3) Determine the volume of the cylinder in cm^3
Procedure 2:
1) Measure mass of small graduated cylinder with 10 mL of water
2) Measure mass of empty graduated cylinder
3) Subtract to determine mass of just the water
4) Divide by 10 to find mass of 1 mL of water
Formulas:
Percent error = (a-e/a) x 100 a = accepted e = experimental
Diameter=(2)r
Volume=pi x r squared x height
