4. A solution is prepared by taking a clean and dry 50.00 mL volumetric flask. Some sucrose (Mm 342.2 g/mol) is added to the flask with the following mass measurements recorded:
mass of empty volumetric flask: 142.88 g
mass of weighing dish + sucrose: 29.83 g
mass of weighing dish after adding sucrose to volumetric flask: 24.62 g
Some water is added to the flask, the solution stirred until all the sucrose is dissolved. Then water is added carefully to the mark on the flask. The filled flask is then weighed again.
mass of filled volumetric flask: 187.30 g
What is the mole fraction of water? Answer to 3 decimal places.
A chemistry student must write down in her lab notebook the concentration of a solution of sodium hydroxide. The concentration of a solution equals the mass
of what's dissolved divided by the total volume of the solution.
Here's how the student prepared the solution:
• The label on the graduated cylinder says:
empty weight: 6.20 g
• She put some solid sodium hydroxide into the graduated cylinder and weighed it. With the sodium hydroxide added, the cylinder weighed 34.241 g.
• She added water to the graduated cylinder and dissolved the sodium hydroxide completely. Then she read the total volume of the solution from the
markings on the graduated cylinder. The total volume of the solution was 61.69 mL.
What concentration should the student write down in her lab notebook? Be sure your answer has the correct number of significant digits.

7) 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 1.328-g tablet reacted
with 40.00 mL of hydrochloric acid (density: 1.140 g/mL), carbon dioxide gas was given off and
the resulting solution weighed 46.699 g. Calculate the number of liters of carbon dioxide gas
released if its density is 1.81 g/L.
