CHE 101 Lab 7: Estimating Avogadro’s Number. Complete Solution.Purpose: The purpose of this lab is to learn how to use Avogadro’s Number to estimate the number of atoms, knowing the mass and volume of an object. Pre-laboratory Questions 1. The stearic acid/hexane solution contains 0.1 g of stearic acid per 1 mL of solution. What is the molarity of this solution? Stearic acid’s molecular mass is 284.48 g/mol. The number of moles in 1 mL solution is 0.1g /284.48 g/mol = 0. mol. Mol...

Avogadro's Number in honor of Amadeo Avogadro () The mole (mol) The unit for counting atoms. The mole is a unit for counting just as a dozen or a ream or a gross is used to count. Atomic mass for an element The average relative mass of all the isotopes for the element. 1 mole atoms = 1 mole molecules = The atomic mass of an element in grams contains (2) The atomic mass of an element in grams contains...
