Information: Significant Figures! Easy to count unless there are zeroes involved. Here are some rules: 1) Never ever count leading zeroes. 2) Always count zeroes between two non-zero digits. When there is a decimal, count zeroes after non-zero digits. 2. How many significant figures does each value contain? For numbers with zeroes present, give the rule(s) you used to determine the correct number of significant figures. \begin{tabular}{llll} 4.760102ps & Rule(s)_ Rule(s) \\ 0.0012m & & 5017km & Rule(s)_(s) \\ 40g & 350.K & Rule(s) \\ \hline Rule(s)_ & 6.0200A \end{tabular} The beauly of scientific notation is that there is NO ambiguity about significant figures! Information: Recall that for multiplication and division, count significant figures and express the answer to the least number of sig figs. For addition and subtraction, only go to the least number of decimal places in the question 3. Express the results of the following calculations to the correct number of significant figures. Include units, and remember you cannot add or subtract different units. 5.33m9.9629103m18.943m 543.7g+568.45627mL (be careful, very, very careful) 14.37mL+251.5mL
