5. Unit 7: Rules of Numbers—Molesanity How do we calculate the number of atoms and moles using Avogadro’s number? 7.1 • Catalyzing thoughts • Mr. Walters wants to organize a pizza party for those students show a 10% improvement in grades for the next quarter. Two pizzas will need to be ordered for each group of 10 students. • How many pizzas would have to be ordered for 20 students? • How many pizzas would have to be ordered for 30 students?

6. Unit 7: Rules of Numbers—Molesanity How do we calculate the number of atoms and moles using Avogadro’s number? 7.1 • Catalyzing thoughts • How about making that pizza: • To make 1 pizza, it requires 50 pepperonis, 2 pounds of cheese and 1 pound of flour. • 50 pepperonis + 2 pounds of cheese + 1 pound of flour = 1 pizza • If you had 150 pepperonis, how many pizzas could you make? Assuming you had an unlimited supply of the other ingredients. • If you had 4 pounds of cheese, how many pizzas could you make Work Period Summary Mini-Lesson Exit Slip Do Now Introduction
