Chapter 18: Q6TY (page 443)

Describe a different set of dilutions to produce 3 mg Fe/mL from 1 000 mg

Fe/mL

Short Answer

Expert verified

Dilute 10 mL of stock to 100 mL to getFe=100渭驳贵别/mL. Dilute 3x1.00mLof the new solution up to 100 mL to get3渭驳贵别/mL

Step by step solution

01

Calculate concentration:

ConcentrationofFe=(Volumeofsolutiondiluted)Volumeofstocksolution(InitialconcentrationofFe)

Given,

Volume of solution diluted =10mL

Volume of stock solution =100mL

Initial concentration of Fe =1000渭驳/mL

Substitute in above equation,

Concentration of Fe =10mL100mL1000渭驳/mL

Concentration of Fe =localid="1663670473584" 100-渭驳/mL

localid="1663670938364" ConcentrationofFe=VolumeofsolutiondilutedVolumeofstocksolution(NewconcentrationofFe)

ConsidernewconcentrationofFe=100渭驳/mL

ConsidernewconcentrationofFe=3mL100mL100渭驳/mL

ConsidernewconcentrationofFe=3渭驳/mL

In formaldehyde, the transition n鈫�蟺*(T1)occurs at 397 nm,and the n鈫�蟺*(S1)transition comes at 355 nm. What is the difference in energy (kJ/mol) between the S1andT1states? This difference is due to the different electron spins in the two states.

(a) How much energy (in kilojoules) is carried by one mole of photons of red light with位= 650 nm?

(b) How many kilojoules are carried by one mole of photons of violet light with位= 400 nm?

A compound with molecular mass 292.16g/molwas dissolved in a 5 - mLvolumetric flask. A1.00 - mLaliquot was withdrawn, placed in a 10 - mLvolumetric flask, and diluted to the mark. The absorbance atwas in 0.427 i acuvet. The molar absorptivity at 340nm is蔚340=6130M-1cm-1

(a) Calculate the concentration of compound in the cuvet.

(b) What was the concentration of compound in the 5 - mL flask?

(c) How many milligrams of compound were used to make the 5 - mLsolution?

Standard addition. Selenium from 0.108 g of Brazil nuts was converted into the fluorescent product in Reaction 18-15, and extracted into 10.0 mL of cyclohexane. Then 2.00 mL of the cyclohexane solution were placed in a cuvet for fluorescence measurement. Standard additions of fluorescent product containingSe/mL are given in the table. Construct a standard addition graph to find the concentration of Se in the 2.00-mL unknown solution. Find the wt%of Se in the nuts and its uncertainty and 95% confidence interval
