Data Comprehension – Solubility Rules – Level 2 Use the table below for any solubility related questions.   Which of the following molecules would be soluble in water?

Precision and Accuracy – Level 1 A general chemistry student took the mass of a sample of Solution Q five times. The following table includes the results of those five measurements. Measurement # 1 2 3 4 5 Mass (g) 14.005 14.006 14.005 14.004 14.006 The true value of solution Q was 15.765 g. The lab holds 5% as the maximum tollerance for accuracy and/or precision. From this it would be reasonable for the student to conclude that the balance is _________________.

Glassware Accuracy – Level 2 Rank the following glassware in terms of accuracy from most to least. I: BurretII: Volumetric FlaskIII: Graduated CylinderIV: BeakerV: Disposable Pipette (ungraduated)

Density and Concentration – Level 3 A series of several standard solutions of varying concentrations were prepared by a chemistry lab instructor for students to use in lab. The density of these solutions were measured and the following calibration curve was constructed.  The students were given data for two unknowns (Unknown A and B) .  The density of Unknown A was 1.0921 g/mL.The concentration of Unknown B was 1.756 M. What is the concentration of Unknown A and the density of Unknown B?
