A stock solution of FD&C Yellow No. 5 (Tartrazine, 234.3 g/mol) was prepared by placing 5.16 g in a 250-mL volumetric flask and diluting to 250 mL with distilled water. A standard solution A is prepared by adding 9.29 mL of stock solution into 25.0 mL volumetric flask and diluting to 25.0 mL with distilled water. Calculate the molar concentration (mol/L) of the standard solution A prepared. Report your answer to 4 decimal places. NOTE: Question asks to calculate the concentration of solution A, not the stock solution.

Tris(pentatluorophenyl)borane, commonly known by its aeronym BARF, is frequently used to initiate polymerization of ethylene or propylene in the presence of a catalytic transition metal compound. It is composed solely of C, F, and B; it is 42.23% C and 55.66% F by mass. a. What is the empirical formula of BARF? b. A 2.251-g sample of BARF dissolved in 347.0 mL of solution produces a 0.01267-M solution. What is the molecular formula of BARF?

The active ingredient in a certain toilet cleaner that claims to 'remove lime scale and rust' is hydrochloric acid of approximate concentration 10.9 mol/L. To analyze this toilet cleaner, a quality control chemist first delivered a 10-mL aliquot of the toilet cleaner into a 250-mL volumetric flask, then made up the diluted solution. She then titrated a 25 mL aliquot of this diluted solution against standard sodium hydroxide solution of concentration 0.46 mol/L. The expected titre (or volume of the titrant in mL) would be approximately:
A solution of HClO4 was standardized by dissolving 0.4008 g ofprimary-standard-grade HgO in a solution of KBr: HgO(s) + 4Br- + H2O → HgBr4 2- + 2OH- The liberated OH2 consumed 43.75 mL of the acid. Calculate themolar concentration of the HClO4.
1. A sample of pure sodium oxalate, Na2C2O4 , weighing 0.2856 g is dissolved in water, sulfuric acid is added, and the solution titrated at 70°C , requiring 45.12 mL of a KMNO4 solution. The end point is overrun and back-titration is carried out with 1.74 mL of a 0.1032 N solution of oxalic acid. Calculate the normality of the KMNO4 solution. Hint: A redox reaction is involed between oxalate and permanganate. Look at the changes in oxidation state by determining the balanced redox reaction: 5C20,2 + + 2MN2+ 2 Mn04 + 10H* → 10CO2 + 8H20
