Answer:

The wavelength the student should use is 700 nm.

Explanation:

Attached below you can find the diagram I found for this question elsewhere.

Because the idea is to minimize the interference of the Co⁺²(aq) species, we should <u>choose a wavelength in which its absorbance is minimum</u>.

At 400 nm Co⁺²(aq) shows no absorbance, however neither does Cu⁺²(aq). While at 700 nm Co⁺²(aq) shows no absorbance and Cu⁺²(aq) does.

A piece of wood displaces 12.5 mL of water and has a density of 0.97 g/ml. what is the mass of the piece of wood? what will happ
mr Goodwill [35]

Density=0.97g/mL

Volume=12.5mL

\\ \sf \longmapsto Density=\dfrac{Mass}{Volume}

\\ \rm\longmapsto Mass=Density(Volume)

\\ \sf \longmapsto Mass=0.97(12.5)

\\ \sf \longmapsto Mass=12.125g
