1. A 4.24 g sample of a laboratory solution contains 1.42 g of acid. What is the concentration of the solution as a mass percentage? 2. Isopropyl alcohol is mixed with water to produce a solution that is 35.0% alcohol by volume. How many milliliters of each component are present in 645 mL of this solution?
y D a -h 14. The unknown tablet is prepared for analysis in two steps. The tablet is crushed into a powder and then dissolved into a 250 mL volumetric flask with dilute acetic acid. A diluted powder solution is prepared by transferring 25.00 mL of the original powder solution into a 50 mL volumetric flask and diluting to volume with dilute acetic acid. Then 1.00 mL of the diluted powder solution is added to each of the standard addition flasks; each flask has a total volume of 10.00 mL. The unknown's riboflavin concentration in the standard addition solutions is determined to be 1.41 ppm. What is the riboflavin concentration (ppm) in the unknown powder solution? 2.82 21.2 14.1 28.2
The label on a bottle of “organic” liquid fertlizer concentrate states that it contains 7.40 grams of phosphate per 100.0 mL and that 16.0 fluid ounces should be diluted with water to make 32.0 gallons of fertilizer to be applied to growing plants. What is the phosphate concentration in grams per liter in the diluted fertilizer? (1 gallon= 128 fluid ounces)
1 of 4 Watch the video that shows using the dilution method to make a solution of known concentration. Note that while the video shows the use of a beaker, in the lab we typically use a volumetric flask to make the diluted solution. The stock solution of KMNO, has a concentration of 2.6 x 10ª M. The pipette has a volume of 10.0 mL. What is the amount of KMNO. delivered to the solution, in moles? mol Submit When using the dilution method to prepare a solution of known concentration, remember that the total amount of solute is the same in both the measured volume of the more concentrated stock solution and in the dilute solution created. This means we can use a simple ennation (Emation 4 2) to calculate the volume or concentration of either the stock solution or the more dilute solution Fauation 4 2 is stv hulu W
Part 1: 8.132g of Mg(NO3)2 are dissolved in 950.0 mL of water. Calculate the molarity of the Mg(NO3)2 solution. Part 2: Calculate the molarity of a solution made by dissolving 2 g of glucose in sufficient water to form exactly 50 mL of solution. Part 3: If 55 grams of Barium nitrate were added to water to make a solution of 250 mL what owuld be the molarity of the resulting solution.
Mass of crucible and cover 12.73g 2. Mass of crucible, cover, and sample 24.11g 3. Mass of original sample 24.11- 12.73g= 11.97g 4. Mass of crucible, cover, and sample after 1st heating 20.01g 6. Mass of crucible, cover, and sample after 2nd heating (assume that this step was done) 19.98 g 7. Total mass lost by sample during heating what is the percentage of water in the sample? and what is the total mass lost by the sample?
A 1.53 g sample of a mixture of FeCl2 and Fe(NO3)2 is treated with excess AgNO3(aq). The precipitate is filtered off, dried and weighed. The dried precipitate weighs 1.92 g. What is the percentage by mass of FeCl2 in the original mixture? Your answer must be accurate to two significant digits. Keep several extra digits in your calculations and round off only at the end. Do not include the percent sign (%) as part of your answer. Molar masses (in g mol−1): N, 14.01 O, 16.00 Cl, 35.45 Fe, 55.85 Ag, 107.9
Deionized water is added to 138.0 mL sample of 1.103 M oxalic acid to dilute it to 0.436M. What volume of water, in milliliters, was added to dilute the sample? Enter your answer in the box, rounded to the correct number of significant figures.
What volume (mL) of 12 M HCl was required to react with the Mg? The data I have for you is this: Mg+2HCl-->MgCl2+H2 is the chemical equation. The mass of magnesium is 0.0273 grams and the moles is 0.001123 The moles of HCl that were consumed in the reaction was 0.002246 moles With this data, I need to know how we can get the volume (mL) of 12 M HCl was required to react with the Mg?
Calculate the each initial CONCENTRATION for Pb(NO3)2 and KI before filling-out this chart. (Refer t Steps 1 and 2 of the procedure. Use the formula for Molarity to calculate the concentration of each salt after preparing the solution from the solid crystals dissolved in 100 mL of water. Do this for Lead (II) Nitrate and KI separately. Then use the dilution formula (starting with the initial concentration) for EACH beaker – each will have a the same total volume, but different volume of each solution added for each beaker. In short, FOR EACH BEAKER, multiple the concentration for Pb(NO3)2 with the concentration of KI.

a. A 250.0-mL solution of sodium hydroxide was prepared by dissolving pure NaOH(s) in deionized water. It required 21.37 mL of 0.1127 M sulfuric acid to completely neutralize 39.29 mL of this sodium hydroxide solution. Calculate the mass, in units of g, of NaOH(s) that was dissolved to make the 250.0-mL solution. Enter your answer in decimal notation using 3 significant figures; i.e., enter 0.03478 as 0.0348 b. In an experiment, 23.24 mL of 0.235 mM silver nitrate are mixed with 9.12 Ml of 0.205 mM sodium phosphate. Assuming 100% yield, what is the concentration, in units of μM, of phosphate in the solution. Assume that the volume of the solid formed is negligible. Enter your answer in decimal notation using 3 significant figures; i.e. enter 2.579 as 2.58.
