13. Rules of Significant Figures Use http://en.wikipedia.org/wiki/Significance_arithmetic Use http://en.wikipedia.org/wiki/Significance_arithmetichttp://en.wikipedia.org/wiki/Significance_arithmetic How do we know how many figures (numbers) to write when we are adding or subracting 2 or more numbers? How do we know how many figures (numbers) to write when we are adding or subracting 2 or more numbers? –Using this information, find the answer to the following:  2.1 + 2.11 =  15 + 5 + 6.12=  86.232 – 5.00 = How do we know how many figures (numbers) to write when we are multiplying or dividing 2 or more numbers? How do we know how many figures (numbers) to write when we are multiplying or dividing 2 or more numbers? –Using this information, find the answer to the following: –35.72 (0.00590) = –6810.2 / 2.4 = –4450 ÷ 5.00 =

16. Dimensional Analysis Try this website: http://www.chemcollective.org/stoich/di mensionalanalysis.php Try this website: http://www.chemcollective.org/stoich/di mensionalanalysis.php http://www.chemcollective.org/stoich/di mensionalanalysis.php http://www.chemcollective.org/stoich/di mensionalanalysis.php  Because there are two different units for any measurement, we need to be able to convert between the two.  Common conversions: (You will be given these, you do not have to memorize them! YAY!)

17. Dimensional Analysis Steps –Write what you know –Form a ratio using your conversion charts. –Be sure your units cancel out –Multiply across the top and divide by what is on the bottom. –Check your number of significant figures. –Make sure your answer makes sense.
