2. While there were no calculations requi mbar conversions using dimensional analysis and still need to know how to do unit the proper number of significant figures. With that in mind, answer the questions below 1. How many significant figures are in each of the fol lowing quantities? a. 0.008 750 L 4 b. 3.40 x 10 m 2 c. 5 630 g 3 Si Convert 0.000 065 80 to scientific notation (without rounding). If a 6.00% (w/v) citric acid solution contains 6.00 grams of citric acid in every 100.0 mL of the solution, how many grams of citric acid are present in 385 mL of the 5.00% (w/v) solution? Show your work using dimensional analysis and report your answer with the correct number of significant figures. 3. 100AL %3D lo0g What volume of the 6.00% (w/v) citric acid solution described above would be needed to provide 425 mg of citric acid for a reaction? For full credit, show your work using a single dimensional analysis grid (or one chain of conversion factors) and report your answer with the…

34. Convert 4.58 x 10³ cm³ to each unit. a. L b. mL c. gal d. qt The m in the equation for density is in italic type, meaning that it stands for mass rather than for meters. In general, the symbols for units such as meters (m), seconds (s), or kelvins (K) appear in regular type, while those for variables such as mass (m), volume (V), and time (t) appear in italics.
