Document Summary
No!: endotherm: an organism that is warmed by heat generated by its own metabolism, ex. Tiger, polar bear, penguins: ectotherm: an organism who body temperature is set by the environment, ex. How to calculate the mass of a molecule: molecular mass= sum of all the atomic masses in the molecule. *** look at pgs 51-52 in text!: molarity is the number of moles per liter of solvent, 1 molar solution= a solution containing 1 mole of a substance per 1 liter of solution. 1 m solution = 1 mole of substance/1l of solvent. Tells you how concentrated a given solution is: ex. How much table salt would one add to 1 liter of water to obtain a 2m solution? (add the mass of the elements and multiply x2: 23+35=58 1m nacl, answer: 116 grams look at pics for examples. Electron orbitals: 1st shell =2 electrons max, 2nd and 3rd shell =8 electrons max inner shells are filled first.
