25 4. In an experiment a student was asked to measure the density of solid titanium. She was given a small flask and determined the mass to be 23.574 gwhen empty and dry. She then did the following steps. a. She completely filled the flask with water (VaskVH) and weighed the full flask, recording a mass of 25.817 g at 25 °C. At this point, the volume of water added is equal to the total volume inside the flask. The density of water at 25 °C is 0.99704 g/cm3. b. She poured out the water and dried the flask. She then added some pieces of titanium to it. The flask plus the titanium had a mass of 27.404 g. Leaving the titanium in the flask, she completely filled the flask the rest of the way with water. The mass for the flask with the titanium +water was measured to be 28.799 g. From the data given, calculate the following to the correct number of significant figures.

4. In an experiment a student was asked to measure the density of solid titanium. She
was given a small flask and determined the mass to be 23.574 gwhen empty and dry.
She then did the following steps.
a. She completely filled the flask with water (VaskVH) and weighed the full flask,
recording a mass of 25.817 g at 25 °C. At this point, the volume of water added
is equal to the total volume inside the flask. The density of water at 25 °C is
0.99704 g/cm3.
b. She poured out the water and dried the flask. She then added some pieces of
titanium to it. The flask plus the titanium had a mass of 27.404 g. Leaving the
titanium in the flask, she completely filled the flask the rest of the way with water.
The mass for the flask with the titanium +water was measured to be 28.799 g.
From the data given, calculate the following to the correct number of significant figures. All
work must be show to receive credit.
