Question
Question 1: Justin followed the procedure described in the lab handout to prepare a solution in which approximately 12 g of sugar was dissolved in enough water to yield 100.0 mL of solution.  He recorded the following data on his data sheet:

Mass of Empty Stoppered Flask (Column A) = 65.649 g
Mass of Sugar (Column B) = 12.674 g
Mass of Stoppered Flask with Solution (Column C) = 170.030 g

What should Justin record as the mass of the solution (Column D) on his data sheet? You must Include the correct number of significant figures in your answer!
 
Question 2: Use the data given in Question 1, and your answer to that question, to calculate the density of the sugar solution (Column E in the data table).  When the volumetric flask is filled to the mark, it contains 100.0 mL of solution (i.e. the solution volume is known to 1 decimal place).

You must include the correct number of significant figures in your answer!
