THIS IS AN EXAMPLE OF WHAT THE RESPONSE TO THIS QUESTION SHOULD LOOK LIKE. APPLY THIS TO THE QUESTION GIVEN BELOW! Question: calculate the density of a solid object if the mass is 2.335 g and the volume was determined by water displacement. The initial volume was 22.5 mL and the final volume was 32.0 mL. SHOW ALL WORK FOR FULL CREDIT. ANSWER: D = m/V = 2.335 g/(32.0 mL-22.5 mL) = 0.25 g/mL OR D = m/V m=2.335 g; V = 32.0 mL-22.5 mL = 9.5 mL Then D = 2.335 g/9.5 mL = 0.25 g/mL A titration reaction between solutions of strontium hydroxide and phosphoric acid is allowed to reach the equivalence point.

Beaker directions: • Measure the liquid in the beaker. Look at what the lines stand for (these are very limited in their ability to measure). Account for all digits on the instrument and then add 1 estimated digit. • If there is not a line for a place value (1, 2, 3...), then that is the furthest you can estimate!
