Kool-Aid contains Allura Red dye. A student makes a Kool-Aid solution by diluting 61.2 mg of Kool-Aid with water to a total volume of 25.00 mL using a volumetric flask. Because this solution is too concentrated (measured absorbance > 1.0), the student then dilutes a small sample of the Kool-Aid solution by taking 0.500 mL of the solution and mixing it with 0.500 mL of water (a ½ dilution). The absorbance of the ½ diluted solution is 0.315. Using the Beer’s Law curve, determine the concentration of the dye in the original Kool-Aid.

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.

Adouble-strand no. 60 roller chain is used to transmit power between a 13-tooth driving sprocket rotating at 300 rev/min and a 52-tooth driven sprocket. a) what is the allowable horsepower of this drive? b) estimate the center-to-center distance if the chain length is 82 pitches. c) estimate the torque and bending force on the driving shaft by the chain if the actual horsepower transmitted is 30 percent less than the corrected (allowable) power.
