1. Mole Dimensional Analysis 10 th Grade ATC Lesson November 15, 2011

2. Student’s Instructions 1.For each question, set up the dimensional analysis that shows how to solve each question 2.Since each teacher is not equipped with a calculator, the “set up” is all that is required. 3.Submit the assignment to your science teacher.

3. For example… Given 12.210 grams of carbon, how many atoms do you have? Your Answer:

4. Set up the Dimensional Analysis for the following… 1.Given: 154.8 moles of silicon tetraiodide a)What is the formula for this compound? b)6.02 x 10 23 molecules = 1 _________ c)Set up the dimensional analysis to find the number of molecules in the given amount

5. 2. Given: 65.8 g of dinitrogen tetroxide a) What is the formula for this compound? b) The mass of nitrogen from the periodic table is 14 g and the mass of oxygen from the periodic table is 16 g. What is the mass of one mole of this compound? c) Set up the problem to show how many moles are in the given sample.

6. TURN YOUR WORK IN TO YOUR SCIENCE TEACHER We, your science teachers, actually do grade the ATC work and count it as a daily grade.
