A chemist must dilute of aqueous aluminum chloride solution until the concentration falls to . He'll do this by adding distilled

Answer:

0.257 L

Explanation:

The values missing in the question has been assumed with common sense so that the concept could be applied

Initial volume of the AICI3 solution $=23.1 \mathrm{mL}$

Initial Molarity of the solution $=833 \mathrm{mM}$

Final molarity of the solution $=75.0 \mathrm{mM}$

Final volume of the solution $=?$

From Law of Dilution, $M_{f} V_{f}=M_{i} V_{i}$

$\Rightarrow V_{f}=\frac{M_{i} V_{i}}{M_{f}}=\frac{833 \mathrm{mM} \times 23.1 \mathrm{mL}}{75.0 \mathrm{mM}}=256.564 \mathrm{mL}=0.256564 \mathrm{L}=0.257 L$

Final Volume of the solution $=0.257$

A smaple of 1cm cuvette gives an absorbance reading of 0.558. if they absorptivity for this sample is 15000l/(mol.cm), what is t

Mazyrski [523]

To solve this problem, we use Beer's Law: A= ε.l.c
A is the absorbance- 0,558
ε is the molar absorptivity- is 15000 L⋅mol-1cm-1
l is the length of the cuvette- 1 cm
c is the molar concentration

Applying the formula,
0,558= 15000 x 1 x c
0,558/15000= c
c= 3.72×10⁻⁵ mol⋅L⁻¹
