10.0 mL of a salt solution has a mass of 12.8 g. The solution is evaporated to dryness and the solute has a mass of 3.5 g. What is the mass percent of the salt solution?
The great French chemist Antoine Lavoisier discovered the Law of Conservation of Mass in part by doing a famous experiment in 1775. In this experiment Lavoisier found that mercury(II) oxide, when heated, decomposed into liquid mercury and an invisible and previously unknown substance: oxygen gas. 1. Write a balanced chemical equation, including physical state symbols, for the decomposition of solid mercury(II) oxide (HgO) into liquid mercury and gaseous dioxygen. 2. Suppose 53.0mL of dioxygen gas are produced by this reaction, at a temperature of 50.0°C and pressure of exactly 1atm. Calculate the mass of mercury(II) oxide that must have reacted. Be sure your answer has the correct number of significant digits.
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.

esc One way the U.S. Environmental Protection Agency (EPA) tests for chloride contaminants in water is by titrating a sample of silver nitrate solution. Any chloride anions in solution will combine with the silver cations to produce bright white silver chloride precipitate. Suppose an EPA chemist tests a 250. mL sample of groundwater known to be contaminated with copper(II) chloride, which would react with silver nitrate solution like this: CuCl₂(aq) + 2 AgNO3(aq) → 2 AgCl(s) + Cu(NO3)₂(aq) C The chemist adds 90.0 mM silver nitrate solution to the sample until silver chloride stops forming. She then washes, dries, and weighs the precipitate. She finds she has collected 6.0 mg of silver chloride. olla Calculate the concentration of copper(II) chloride contaminant in the original groundwater sample.
