2. Scientific Notation Number of atoms in a mole 602300000000000000000000 This size of an electron 0.0000000000000028

3. M.8.EE.2: use numbers expressed in the form of a single digit times an integer power of 10 to estimate very large or very small quantities, and to express how many times as much one is than the other. For example, estimate the population of the United States as 3 × 10 8 and the population of the world as 7 × 10 9, and determine that the world population is more than 20 times larger.
