Measuring devices and significant figures an experiment that yields numerical data requires appropriate measuring devices this lab is about you learning to read these devices correctly and to record the correct number of significant figures for each measurement. The more place values the greater the certainty in the accuracy of a measurement.

With this ruler one knows the length of the paper is more than 10 cm but definitely less than 11 cm.
Measuring with significant figures worksheet-1_1_1.pdf. Significant figures in operations. In the ruler illustration below the bottom ruler gave a length with 2 significant figures while the top ruler gave a length with 3 significant figures. The number of significant figures usually depends upon the measuring device.
When explaining how significant figures work discuss the importance of the number of place values in a measurement. Find the first non zero on the left then count all digits to the. Hence the measurement with the mm ruler would have a greater number of significant figures.
Because 8 315 has four significant figures the number 298 with three significant figures limits the result therefore the answer should have only three significant figures. Always retain at least one more significant figure in your calculations than the number you are entitled to report in the result. Reading instruments with significant figures teacher key notes.
The significant figures in a measurement consist of all the certain digits in that measurement plus one uncertain or estimated digit. An estimate is that it is 0 7 or 0 8 beyond 10 cm. Remember that significant figures apply to your reported result.
Practice problems for significant figures. To measure a figure with rulers with different scales and to us these measurements to determine areas and volumes to the proper number of significant. For addition and subtraction operations the result should have no more decimal places than the number in the operation with the least precision.
There are additional rules regarding the operations addition subtraction multiplication and division. For example when performing the operation 128 1 1 72 0 457 the value with the least number of decimal. The calculation is correctly represented as 8 315 298 three figures two significant figures limiting measurement two significant figures in the answer.
Measuring the length with cm ruler 1. Find the first non zero on the right then count all digits to the. Every digit in scientific notation is significant.
For example a centigram balance provides two decimal places while an analytical balance can be read to four. Always retain at least one more significant figure in your. If the decimal is.
Rounding off your numbers in the process can lead to errors. This worksheet will give brief instruction on how to use rulers graduated cylinders and balances but the focus is on doing so within the rules for significant figures. Measuring with significant figures worksheet chemistry is one of the first classes where the importance of measuring accurately and precisely becomes clear.
In a correctly reported measurement the final digit is. If the decimal is.
