A 4.00 ( ± 0.01 ) mL Class A transfer pipet is used to transfer 4.00 mL of a 0.255 ( ± 0.004 ) M Cu 2 + stock solution to a 100.00 ( ± 0.08 ) Class A volumetric flask. Deionized water is used to bring the flask to volume. Calculate the concentration of the diluted soluion in the volumetric flask and report its absolute uncertainty.

1) 20.0 mL of 0.01 M AgNO3 and 30.0 mL of 0.010 M K2CrO4 are mixed together and allowed to react. Will a precipitate form? What will be the molarities of the silver ion and chromate ion at equilibrium? 2) Tooth enamel is composed of hydroxyapatite, whose simplest formula is Ca5(PO4)3OH and whose corresponding Ksp = 6.8 x 10^-27. As discussed, fluoride in fluorinated water or in toothpaste reacts with the hydroxyapatite to form fluoroapatite, Ca5(PO4)3F whose Ksp = 1.0...

You prepare an equilibrium mixture by combining 4.00 mL 0.00129 M Fe3+ with 0.100 mL 0.00582 M SCN-. What is [Fe3+]o for this mixture? Enter the numerical value to 3 significant figures, without units. (You may enter the value using E-format scientific notation, e.g., 1.23×10-4 would be entered as 1.23E-4 -- no spaces, capital E.)
