MASS VS. VOLUME LAB • Goal: To determine the relationship between volume and mass for Zinc. • Pre-Lab 1. Goal 2. Materials list 3. SPECIFIC Procedure (MINIMUM 12 pieces of Zinc) 4. Data Table(s) • Post lab 1. Graph (Mass on x-axis, Volume on y-axis) 2. Questions

POST LAB QUESTIONS • Calculate the slope of the line. (Show all work for full credit) • What are the units of the slope of the line? • What is the general relationship between volume and mass? • Is there a direct or indirect relationship between mass and volume? Explain.

SAMPLE DATA • Put Mass on Y and Volume of Zinc on X • If you had any data that had the exact same volume of Zinc for any of the pieces of Zinc, graph this data below! • If any of your volumes of m (g) v (m. L) 2. 32 0. 32 Zinc were zero, use 4. 34 0. 61 this data 5. 72 0. 80 6. 4 0. 90 7. 01 0. 98 9. 22 1. 29 10. 9 1. 53

MORE POST LAB 1. What are the units of the slope of the graph below? 2. What is the meaning of the slope below? 3. What is density as it relates to matter? 4. When you found the slope of the line, what did Mass (g) you actually solve for with each of the metals? Volume (m. L)

POST LAB DISCUSSION • Do all of the pieces of Zinc from the lab have the • • same density? If you massed a larger sample of metal, would the density change for that metal, explain? When you found the slope of the line, what did you actually solve for with each of the metals? What are some possible reasons you did not come up with the correct density? List at least 2 possible errors. Why did you need to use sample data?
