For the Shaefer-Fulton endospore stainmethod, the working solution of safranin ismade by combining 10 mL of stock solutionwith 90 mL of distilled water. If you need toproduce 1,046 mL of working solution, howmany grams of safranin O will be required tomake the smallest batch of stock solutionpossible?• Report your answer in grams usingstandard decimal notation rounded totwo decimal places.• Include trailing zeros.• Do not include the units in your answer。 If your answer is 100.105 g it wouldbe reported as 100.11。 If your answers was 100.203 g itwould be reported as 100.20

Show your complete solution and round-off your answers to four decimal places. A 0.1093-g sample of impure Na2CO3 was analyzed by the Volhard method. After adding 50.00 mL of 0.06911 N AgNO3, the sample was back titrated with 0.05781 N KSCN, requiring 27.36 mL to reach the end point. Calculate the % purity of the Na2CO3 sample. Answer = _% Na2CO3
An aqueous solution was created by placing 0.018 g of NaCl into a 50 mL volumetric flask and diluting to volume with deionized water. (Because the amount of solute is small, you may assume that the volume & density of the solution is equal to the volume & density of the solvent where appropriate.) Find the concentration in terms of the following units. Report your answers without scientific notation. Only input numbers. Your answers must be expressed to the correct number of significant figures. Any values less than one must have a zero in front of the decimal (e.g. 0.01 not .01) Molarity: M Molality: m Mole Fraction of NaCl (X): Mass % of NaCl: %

1. A student performed this experiment and obtained the following concentration values: 0.02813 M, 0.02802, and 0.02788 M a. what is the mean concentration? b. what is the standard deviation of these results? 3. how would the following errors affect the concentration of Cl- obtained in question 2b? give your reasoning in each case. a. the student read the molarity of AgNo3 as 0.02104M instead of 0.02014M b. the student was past the endpoint of titration when he took the final buret reading.
Calculate the concentration of sugar in this solution using the volume percent equation. For the purpose of this exercise, it can be assumed that the weight of the drink mix is 0.00 g. The volume of the solution is 3 and 1/3 cups. Calculate and record the volume percent (g/mL). (Note that 1 cup = 236 mL). Volume %=Volume of Solute / Volume of Solution ×100% I used 1/2 cup of granulated sugar and 1/2 tsp of the drink mix, and 3 cups of water. 2. Calculate the concentration of each diluted solution using the equation below and the volumes in Table. C1V1=C2V2 Where: C1=concentration of stock solution V1=volume of stock solution C2=concentration of diluted solution V2=volume of diluted solution (This is all the information that I have)
