A tank contains 1000 L of pure water. Brine that contains 0.05 kg of salt per liter of water enters the tank at a rate of 5 L/min. Separately, brine that contains 0.04 kg of salt per liter of water enters the tank at a rate of 10 L/min. The solution is kept thoroughly mixed and drains from the tank at a rate of 15 L/min. Let y(t) be the amount of salt (in kg) aftert minutes. (a) How much salt is in the tank after t minutes? y(t) kg (b) How much salt is in the tank after 30 minutes? (Round the answer to one decimal place.) y(30) = kg

A soft drink contains an unknown mass of citric acid, C3H5O(COOH)3. It requires 6.42 mL of 9.580 × 10−2-M NaOH to neutralize the citric acid in 10.0 mL of the soft drink. C3H5O(COOH)3(aq) + 3 NaOH(aq) → Na3C3H5O(COO)3(aq) + 3 H2O(ℓ) Determine which step in these calculations for the mass of citric acid in 1 mL soft drink is incorrect? Why? n (NaOH) = (6.42 mL)(1L/1000 mL)(9.580 × 10−2 mol/L) n (citric acid) = (6.15 × 10−4 mol NaOH) × (3 mol citric acid/1 mol NaOH) m (citric acid in sample) = (1.85 × 10−3 mol citric acid) × (192.12 g/mol citric acid) m (citric acid in 1 mL soft drink) = (0.354 g citric acid)/(10 mL soft drink) Determine the correct result.
Suppose that you are closing a cabin in the north woods for the winter and you do not want the water in the toilet tank to freeze. You know that the temperature might get as low as 30. C, and you want to protect about 4.0 L water in the toilet tank from freezing. Calculate the volume of ethylene glycol (density = 1.113 g/mL; molar mass = 62.1 g/mol) you should add to the 4.0 L water.
What mass of solid NaOH (97.0% NaOH by mass) is required to prepare 1.00 L of a 10.0% solution of NaOH by mass? The density of the 10.0% solution is 1.109 g/mL.
In the laboratory, a student adds 14.0 g of silver nitrate to a 375 mL volumetric flask and adds water to the mark on the neck of the flask. Calculate the concentration (in mol/L) of silver nitrate, the silver ion and the nitrate ion in the solution.
In the lab, Stock bottles of concentrated solutions can be diluted to make solutions for use with a lab. The dilution formula is C1V1=C2V2; here C= concentration and V= volume, the 1 = initial and 2= final. Use this formula to determine what volume of a 12M Stock solution will be used to make 500mL of a 3M solution. Then determine the volume of water you will add to the calculated amount of Stock solution to dilute it to the proper concentration and volume.
A total of 31.3 ml of 0.15 N NaOH was required to reach a phenolphthalein endpoint in titrating 6.00 g vinegar. Calculate the number of equivalents of acetic acid in vinegar. Calculate the number of grams of acetic acid present in the vinegar. Calculate the percent by weight of acetic acid in vinegar.
Chlor-alkali plants electrolyze NaCl to produce the commodity chemicals caustic soda and chlorine gas. Industrial waste effluent released into waterways from these plants can contain trace amounts of mercury. Legally, the effluent can contain up to 2.50 x 10-9 mol/L of mercury. Determine the minimum volume of water, in megalitres (ML), that must be added to a 1.13 g sample of mercury to dilute the effluent to acceptable levels.(Do not show your work in the space provided; record only your final answer with the correct number of significant digits and the proper units.)

2. In the standardization of an acid and base solution, sodium hydroxide (99.5% by mass) was used. A sample weighing 0.12 gram was dissolved and titrated to the endpoint with the acid solution. The initial buret reading is 5.5 mL. The final buret reading is 28 mL. Calculate the normality of the acid solution.
Which of the following given statements is true? * Dissolved oxygen in large bodies of water may be from the waste product of photosynthesis from algae, seaweed, and other aquatic plants. The normality (N) of a solution is determined by multiplying the molarity of the solution by its volume. In the Winkler Titration Method, the endpoint is determined by the visual indicator, methyl violet. All given statements are false.
A 28.3 mL hydrochloric acid solution was standardized using 0.256 g of sodium carbonate. (Na2CO3 = 106 g/mol; HCl = 36.46 g/mol) Na2CO3 + 2 HCl → 2 NaCl + H2CO3 - What is the mass of hydrochloric acid in grams? - What is the concentration of hydrochloric acid in %w/v?
1) KOH and NaOH are dissolved in water to form a 2.48 molar solution. If 42.9 g of NaOH are used and the resulting solution has a volume of 1673 ml, how much of the pure KOH was in the solution? 2) Sucrose CizH2O1 and ethyl alcohol CH,OH are mixed to form a 14.1 %wt solution. If the density of the solution is 1.15 g/ml, find the molar concentration of the solution.
