how many moles of potassium dichromate (k2cr2o7) are required to prepare a 250-ml solution of with a concentration of 2.16 m?
Eva8 [605]

The moles of potassium dichromate , K₂Cr₂O₇ are required to prepare a 250 mL solution of with a concentration of 2.16 M  is 0.54 mol.

given that :

molarity = 2.16 M

volume = 250 mL = 0.25 L

the molarity is given as :

molarity = number of moles / volumes in L

from this we can calculate the number of moles, we get :

number of moles of K₂Cr₂O₇ = molarity × volume

number of moles of K₂Cr₂O₇ = 2.16 × 0.25

number of moles of K₂Cr₂O₇ = 0.54 mol

Thus, The moles of potassium dichromate , K₂Cr₂O₇ are required to prepare a 250 mL solution of with a concentration of 2.16 M  is 0.54 mol.

A spectrophotometer measures the transmittance or the absorbance, or both, of a particular wavelength of light after it has pass
Cerrena [4.2K]

Answer:Answer: The step that is NOT necessary to complete before a cuvette is placed into the spectrophotometer is option B (Write, in ink, either sample or blank on the side of the cuvette to keep track of them)

Explanation: spectrophotometer is an instrument used to measure the light intensity absorbed after being passed through a solution. Before the absorbance of the sample solution, a solvent solution called blank is used for the calibration of the machine and this blank solvent is placed in a cuvette. The procedure usually comes first before the main sample is processed. Therefore there is no need to

Write, in ink, either sample or blank on the side of the cuvette to keep track of them. This is so since sample and blank is not absorbed at the same time by the machine.
