LAB 14 PERCENT ERROR PROCEDURE 1 The markings

LAB #14 PERCENT ERROR

PROCEDURE: 1) The markings on the sides of a 50 ml, 100 ml and 150 ml beaker will be used to determine the percentage error of their volumes. 2) The formula | E - T | X 100 = ERROR % T E = experimental value (the marking on the side of the beaker) T= theoretical value ( the readings from the graduated cylinder)

PROCEDURE: 20 ml line 3) Use the water in the clear plastic cups to fill the beakers to 20 ml line. This is the E value. Record in your data table. 4) Use the 50 ml graduated cylinder to measure the water in the beaker. Record the amount of water in your data table.

Add 20 ml of water to beaker then pour it into graduated cylinder 50 ml beaker 20 m. L

Add 20 ml of water to beaker then pour it into graduated cylinder 20 m. L

Add 20 ml of water to beaker then pour it into graduated cylinder 150 ml beaker 20 m. L

PROCEDURE: 40 ml line 6) Use the water in the clear plastic cups to fill the beakers to 40 ml line. This is the E value. Record in your data table. • • 7) Use the 50 ml graduated cylinder to measure the water in the beaker. Record the amount of water in your data table. • • 8) Determine the percentage error for each beaker.

Add 40 ml of water to beaker then pour it into graduated cylinder 50 ml beaker 40 m. L

Add 40 ml of water to beaker then pour it into graduated cylinder 100 ml beaker 40 m. L

Add 40 ml of water to beaker then pour it into graduated cylinder 150 ml beaker 40 m. L

9) Use the water in the clear plastic cups to fill the beakers to 60 ml line. This is the E value. Record in your data table. 10) Use the 100 ml graduated cylinder to measure the water in the beaker. Record the amount of water in your data table. 11) Determine the percentage error for each beaker.

Add 60 ml of water to beaker then pour it into graduated cylinder 100 ml beaker 60 m. L

Add 60 ml of water to beaker then pour it into graduated cylinder 150 ml beaker 60 m. L
