MIDTERM REVIEW IN FOUR PARTS
MEASUREMENT: Classify matter using appropriate measurement units and calculations metric conversions (no factor-label method) significant digits scientific notation (converting to/from scientific notation) rounding numbers MEASUREMENT
Try these conversions using the stair step method: 104 km = ___________________ m 2000 mg = ___________________ g 480 cm = ___________________ m 5.6 kg = ___________________ g MEASUREMENT
SIGNIFICANT FIGURES MEASUREMENT
Convert the following numbers into standard notation or scientific notation. 42. 44,500 ______________________ 43. 0.000643 ______________________ 44. 5.78 x 104 ______________________ 45. 5.18 x 10-2 ______________________ MEASUREMENT
MATTER: Classify matter using physical and chemical characteristics. describe physical and chemical changes of matter and give examples calculate density determine if something is a mixture, compound, element, or solution MATTER
Calculating Density If a liquid has a mass of 352g and a volume of 0.546L, what is the density of the liquid? Show the formula, set up the problem and units, and make sure the answer has the correct number of significant digits. MATTER
