14.  Base units are defined units based on an object or event in the physical world: 1. Meter = distance light travels through a vacuum in 1/299,792,458 of a second (or 2.99792458 x 10 -8 seconds) 2. Kilogram = mass of a platinum-iridium cylinder that is stored at constant temperature and humidity

15.  Units made up of a combination of base units: 1. Speed = meters/second 2. Volume = 1.cubic meter (m 3 ) or cubic centimeter (cm 3 ) 2.Liter (or cubic decimeter – dm 3 ) 3.How is this a combination of base units? 3. Density = mass/volume (g/mL or g/cm 3 )

16.  You have a cylinder with a volume of 150 mL and a mass of 75 g. What is its density? 1. Known values: 1. V = 150 mL 2. m = 75 g 2. Formula 1. Density = mass/volume = 75 g/150 mL 2. Density = 0.5 g/mL

17.  If d=m/V, rearrange the formula to solve for m. m = ?  If d = m/V, rearrange the foemula to solve for V. V = ?  Example Problem (p.29)  Assignment: Practice Problems (p.29)
