Final answer:
To determine the molar concentration of chicken egg cytoplasm, spectrophotometry is commonly used, particularly if measuring protein concentrations. It involves comparing the absorbance at a specific wavelength to a standard curve to find the molar concentration.
Step-by-step explanation:
To determine the molar concentration of chicken egg cytoplasm, the appropriate method would depend on the specific component being measured. Option B, spectrophotometry, is a common analytical technique used to measure the concentration of certain solutes in a solution based on the absorption of light. The absorbance reading at a certain wavelength can be used to assess the concentration using a standard curve, which is a graph of known concentrations of a substance versus their absorbance at a particular wavelength. For example, if the objective is to measure protein concentration within the cytoplasm, a spectrophotometer can be used to determine the absorbance at a specific wavelength, typically related to the chromophores of the proteins, and compare it to a standard curve of known protein concentrations to find the molar concentration of proteins in the sample.
Titration, cell fractionation, and atomic absorption spectroscopy are other methods that are used for different types of analyses and may not directly apply to the determination of molar concentrations in chicken egg cytoplasm.
