Weight Change Data from the Osmosis Lab



Please fill in the following data, then submit the form. Your lab protocol explained that you should read the balance to two decimal places. Thus, the error-checking on this Web page includes checking to see if each weight number you enter has the correct number of decimal places. If you do not correctly enter a number, a small dialogue box will pop up asking you to correctly enter the number. In that case, enter the correct number in the space in the dialogue box, and it will be transferred to the appropriate space on the Web form.


Please fill in the requested information.
