A 63 kg patient is in need of intravenous iron supplementation. He was ordered to receive a single intravenous 7 mg/kg dose of iron (III) sulfate (ferric sulfate - Fe2(SO4)3 - MW=399.88 g/mol). Iron (III) sulfate was prepared as a stabilized aqueous solution for this patient by dissolving 775 mg of stabilized iron sulfate salt in water to produce 15 mL of solution. How many milliequivalents of iron (Fe 3+) will the patient receive as a single dose? Assume the salt completely disassociates in solution. Round the answer to two decimal places.

OSHA's Hazard Communication Standard requires chemical manufacturers to evaluate hazards relating to their products and provide a Safety Data Sheet in accordance to the Globally Harmonized System (GHS) in which the use of pictograms (see Figure 1) is required to communicate hazard information. Predict (with reasons) two (2) hazards related to each of the two activities below, and assign two (2) relevant pictograms listed in Figure 1 to each of the two activities. Activity 1: Removing diethyl ether (last opened in 2019) using a rotary evaporator. Activity 2: Using carbon monoxide gas as a reducing agent to reduce iron chloride. Figure 1.

Based on the dissolved solute's properties, we can quantify that solute's concentration are too high to permit an accurate measurement. For example, a spectrophotometer can measure the amount of light that passes through a sample solution for If the solute's concentration is too high, a relatively small amount of incident light having the wavelength that corresponds to the solute's absorption behavior will less light is absorbed, and the detector in the spectrophotometer can generate more reliable data. reach the dete ctor, which results in an inaccurate measurement (consider the result if you blocked the light with an opaque…
