Chapter 0.9, Problem 0.8P
A 1.000 mL sample of acetone, a common solvent sometimes used as a paint remover, was placed in a small bottle whose mass was known to be 38.0015 g. The following values were obtained when the acetone-filled bottle was weighed: 38.7798 g, 38.7795 g, and 38.7801 g. How would you characterize the precision and accuracy of these measurements if the true mass of the acetone was 0.7791 g?

5) A student correctly determines that 17.1 grams of sucrose are needed to make 50 ml of a 1M
solution of sucrose. When making this solution in the lab, the student measured 50.0 ml of water in
a measuring cylinder and added that to a beaker. Then the student massed 17.1 grams of sucrose
and added it to that beaker. She then mixed the solution well and poured the resulting solution into
a graduated cylinder. To her utter shock, the volume of the solution was now 62.0 mL. Explain what
happened.
Describe the steps the student should have taken to prepare a 50.0 ml solution of
1M sucrose.
6) What volume of 0.10 M solution can be prepared using 11.6 g of NaCl?
TUMS is a popular remedy for acid indigestion. A typical TUMS tablet contains calcium carbonate plus some inert substances. When ingested, it reacts with the
gastric juice (hydrochloric acid) in the stomach to give off carbon dioxide gas. When a 1.371 g tablet reacted with 40.00 mL of hydrochloric acid
(density 1.140 ), carbon dioxide gas was given off, and the resulting solution weighed 46.699 g. Calculate the number of liters of carbon dioxide gas
ml
released if its density is 1.81

- A solution is prepared by dissolving table salt, sodium chloride, in water at room temperature. a Assuming there is no significant change in the volume of water during the preparation of the solution, how would the density of the solution compare to that of pure water? b If you were to boil the solution for several minutes and then allow it to cool to room temperature, how would the density of the solution compare to the density in part a? c If you took the solution prepared in part a and added more water, how would this affect the density of the solution?arrow_forwardOn October 21, 1982, the Bureau of the Mint changed the composition of pennies (see Exercise 120). Instead of an alloy of 95% Cu and 5% Zn by mass, a core of 99.2% Zn and 0.8% Cu with a thin shell of copper was adopted. The overall composition of the new penny was 97.6% Zn and 2.4% Cu by mass. Does this account for the difference in mass among die pennies in Exercise 120? Assume the volume of the individual metals that make up each penny can be added together to give the overall volume of the penny, and assume each penny is the same size. (Density of Cu = 8.96 g/cm3; density of Zn = 7.14 g/cm3).arrow_forwardEthanol has a density of 0.789 g cm‐3.
