The value of δ for the [crf6]^3- complex is 182 kj/mol. calculate the expected wavelength of the absorption corresponding to promotion of an electron from the lower-energy to the higher-energy d-orbital set in this complex. (remember to divide by avogadro's number.)

6.63*10-7 m

Explanation:

The energy of one mole of the compound is obtained by dividing by the Avogadro number. Then the wavelength is obtained from

E= hc/wavelength as shown in the question.

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation
