Dimensional Analysis: * In chemistry, there are 2 basic calculations: ↳formula ↳dimensional analysis Equivalence statement: used to create a conversion factor ↳Ex. 1 dozen = 12 eggs * Dimensional Analysis: using conversion factors to change from one unit to another Ex. convert 110. lbs → _kg Step 1: write down what you know 11b = 0.45359 kg Step 2: convert (cancel out) 110.165x 0.45359 kg = 49.9 kg 15 Ex. Convert 26.2 miles to meters 26.2 mix kin 0.62137m = 4.22 x 104 X 1000 m krn L[bigger unit unitation gets the 1 Temperature · boiling points: freezing points: 100°C 0°C conversion Equations: °C °F-32 1.8 °C=25 room 373 K 273 K K= °C + 273 temperature Ex. convert Room Temperature 298 K to °℃ and of 298 K= °C + 273 1.8. 25°C = °F -32.8 18 -273 -273 212°F 45°C °F-32 +32 +32 °F=77 32°F
