Since the slope is in g/mL it represents . . . . . DENSITY 3. Both E and F have the same number of particles. Since particles with larger size have greater mass, then E must have greater mass. Volumes appear equal so E has greater density. (50, 80) 4. a) Equal masses - Pans would be balanced since have same mass on both sides. Equal volumes - A pan would be tilted down because it has greater mass in same volume. For example at 10 mL, B would have mass of 5 g, while A would be 17 g. (60, 30) (0, 0) (0, 0) b) Substance A = 1.6 g/mL Since the slope is in g/mL it represents . . . . . DENSITY Substance B = 0.5 g/mL

To balance, I would need 16 g of B 1.6 g of A 10 mL of A x = 16 g of A 1 mL of A

0.5 g of B 1 g of A 1 mL of A 35 mL of B x x x 1 mL of B 1 g of B d) one e) Sketch a line with a slope of . . . . . . . f) Substance A will sink as it has a larger density (slope) than H2O Accordingly, substance B will float as it has a smaller density (slope) than H2O 0.5 g of B 1 g of A 1 mL of A 35 mL of B x x x = 11 mL of A 1 mL of B 1 g of B 1.6 g of A

Hg 5) Titanium has a density of 4.54 g/mL So . . . . . 10 mL of titanium has a mass of Cu 45.4 g Copper has a density of 8.96 g/mL Ti So . . . . . 10 mL of copper has a mass of 89.6 g Mercury has a density of 13.55 g/mL So . . . . . 10 mL of copper has a mass of 135.5 g 67.75 g So . . . . . 5 mL of copper has a mass of uh oh!
