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
Units made up of a combination of base units:
1.Speed = meters/second2.Volume =
1. cubic meter (m3) or cubic centimeter (cm3)
2. Liter (or cubic decimeter – dm3)3. How is this a combination of base units?
3.Density = mass/volume (g/mL or g/cm3 )
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 mL2. m = 75 g
2.Formula1. Density = mass/volume = 75 g/150 mL2. Density = 0.5 g/mL
If d=m/V, rearrange the formula to solve for m. m = ?
If d = m/V, rearrange the foemula to solve for V. V = ?
