Use a decimal point.] * Your answer Question 4: Consider the information in Question 3. What mass in milligrams of oxalic acid was transferred to the conical flask? [Do not type in the unit. Use a decimal point.] * Your answer
Question 5: Find the mass in grams of sodium hydroxide that will be required to prepare a solution with a concentration of 0.500 mol·dm⁻³ in a 250 cm³ volumetric flask. [Round the answer to three decimal places. Do not type in the unit. Use a decimal point.] * The concentration of the solution prepared in Question 5 is only approximate because sodium hydroxide is not a primary standard. * A- True B- False
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 gMass of Sugar (Column B) = 12.674 gMass of Stoppered Flask with Solution (Column C) = 170.030 gWhat 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!
