Amolecule is known to have a molar absorptivity of 18,650 at a certain wavelength. a spectrometer is tuned to this wavelength and used to measure the absorbance of a solution of this substance in a b = 1 cm cuvette. the indicated absorbance of the sample was 1.04. the tested solution used in the experiment was prepared by dissolving 100 mg of the substance into a 100 ml volumetric flask. what is the molecular weight of the substance / molecule tested?

Hannah is writing a report on how albedo affects the global climate. she’s proofreading her passage for any factual errors. which sentence must hannah correct before submitting her report? earth receives energy from the sun. this energy drives many of the processes on earth, including its climate. some part of this energy is reflected by earth’s surface. we use the term albedo to describe the reflected energy. albedo of an object is the ratio of the reflected radiation to the total radiation reaching the object. a value of 0 means no energy is absorbed by the object, whereas a value of 1 means that all of the energy is absorbed. in this way, the albedo of an object can influence earth’s atmospheric temperature.
