Problem 4-B

Spreadsheet for standard deviation. Lets create a spreadsheet to compute the mean and standard deviation of a column of numbers in two different ways. The spreadsheet here is a template for this exercise.

Step-by-Step Solution:
Step 1 of 3

Chem 115 Review of HS 01/11 -atoms combine to form molecules ^molecules: structure of 2+ atoms chemically bonded and behave as one unit -molecules undergo chemical reactions either by themselves or with others to make new molecules -LAW OF CONSERVATION OF MASS: total mass must not change during a reaction -when calculating atomic mass: Molecular mass = sum of atomic masses AlBr3 = Al (26.982) + Br (79.904) = 266.692 amu (atomic mass units) * 1 AMU = 1.661 * 10^-24 * Avogadro Constant* ^ 1 mole = 6.022 * 10^23 ^mole is similar to a dozen, use moles instead of AMU’s Isotope: same # of protons (Z), different # of neutrons (N) Molarity (M): moles/liter
