Purpose: what is the concentration of the menown Solution? Hypothesis: None. Method: Use the transport Activity - dry run to get the method Independent Variable Dependent Variable (measuring) (changing) Different molarinies of sucrose Procedure: "as given" Data Table: Molarity in bag 0 (H₂0) 0.2 M Sucrose 0.4 M Sucrose 0.6 M Sucrose 0.8 M Sucrose 1.0 M Sucrose Unknown 90 38 40 initial mass (g) 20 10 10 10 10 Calculated channe final mass (g) 10.3 11.2 14.8 10.5 17.2 12.8 .2 Controlled Variables (same) Dialysis tubing, + time. (final mass - initial mass) initial mass .4 X 100 water % change my group Analysis 1. Calculate the percent change in mass for your solutions. Use the workspace in the data table for help. 2. Graph your data & the class average data. Label the independent (x axis) and dependent variable (y axis). Include a title. After plotting both sets of data one best fit STRAIGHT line. 100 Control The tube filled with water D % change class average 4 .8 46 68 30 1.0

3. Use the % change class average for the unknown a. Circle the spot on the best fit line that shows the sucrose concentration of the unknown. .3m 4. What is the relationship between the change in mass and the sucrose concentration in the dialysis bags? The greater the sucrose concentration the greater b. What is the sucrose concentration of the unknown? the ✓ Change. Use the graph to answer # 5 & 6 5. An unknown solution had a percent change of 23%, what is the molarity of the solution? 2M 6. The Molarity of a solution is .7M, what is the percent change? 90% 7. A bag with .2M of sucrose solution and placed it in a cup of .8M sucrose solution. Draw a cup with a bag in it. Put 2 dots in the bag and 8 dots in the cup. b. Draw an arrow that shows the direction the sugar would move C. Would you expect the mass of the bag to increase or decrease? Why? water is going to leave the bay 8. Name and define the process that causes the water move from the cup into the bag? Osmosis Discussing the Data - Class Average vs Group 9. Use the % change my group for the unknown a. Square the spot on the best fit line that shows the sucrose concentration of the unknown. b. What is the sucrose concentration of the unknown? 10. Many times when there are differences in data it is caused by small errors made when setting up the lab, collecting data or processing the data. List 2 sources where an error could have been made. filling the bags massing the bags 11. Is it better to use individual data or class data? Explain. C. you get the same answer as in 3b? Did more data
