Data Analysis
In this lab you will work your data up in a Google Spreadsheet, the template of which can be downloaded on the report page (3.3A: Solutions and Freezing Point Depression Report). There are three sheets in the Google Workbook
Cover page tab
The first tab is always the cover page. As usual you will put your results here.
Solutions tab
The solutions tab is where you will enter your data and calculations for part one. This experiment will also help you refresh the different possible units of concentration and the methods of aquiring them in the lab.
Sig Figs
Always enter data to precision (example a reading for the burette would have two decimal places 2.00mL)
Multiplication and division uses the least number of sig figs (23.004x2.00=46.0)
Addition and subtration use the lowest number of decimal places (1000.0000 +2.00 =1002.00)
Temperature tab
The freezing point depression constant can be found in the Resources tab of any LibreText page (Resources/Reference tables/reference tables/bulk properties/cryoscopic/Melting Point Depression constants) or section 13.4.3.1. But you should become familiar with the blue resources tab on the left of all LibreText pages, as the function like the appendices in a normal textbook.
