a. Carefully work through the sample calculations for this lab ON PAPER. Then, set up the same equations on a separate sheet of paper, but replace the values in the 'Sample Calculations' folder with the ones provided below and complete the calculations:
Mass of the empty 10 mL graduated cylinder: 48.3298 g
Mass of the 10 mL graduated cylinder and water: 58.3108 g
Volume read from the 10 mL graduated cylinder: 9.96 mL
Temperature of the water: 19.8 ºC
b. After finishing your work on paper, record the values here for:
Density =
Mass of water =
Calculated volume of water (held by the graduated cylinder) =
Percent error =
Remember all units and state your answers with the correct digits of precision or significant figures (whichever is appropriate).
Wanted to know how I got this problem wrong, went through it a couple times and didn't get it correct.

4. Suppose that a student performed the experiment and calculations perfectly as directed except that, unknown to the student, the balance was not zeroed but weighed 0.100 g too high throughout the experiment. Would the calculated val- ue for the density of the unknown liquid be correct? That is, would it be equal to, higher than, or lower than the true value.

c) A metal sample has a mass of 7.56 g. The sample is placed into a graduated cylinder previously filled with 20.00 mL of water (enough to cover the sample). If the final volume in the cylinder is 21.68 mL, what is the density of the substance? Consult Table 1.4 on page 19 of the textbook to identify the metal. i) A small crystal has a mass of 7.03 mg The dimensions of the crystal...
