In a hypothetical diesel engine the fuel is compressed from 528mL to 39.7 mL.  This rasies the temperature of the fuel form 25°C to its ignition temperature of 210°C.  If the fuel begins at 1.00atm, what is the pressure of the fuel at its ignition temperature.? Express your answer to 1 decimal place.  Be sure to use the proper abbreviation of the UNITS

In an experiment similar to Perrin's, you counted the concentration of suspended particles in a liquid. When observing the suspension at a depth 9 mm from the bottom of the container, you counted 300 particles per mm. At a depth of 18 mm from the bottom, you counted 150 particles in the same volume. With a third observation at a depth of 20 mm from the bottom, the expected number of particles per mm is closest to which value? 100 particles per mm3 64 particles per mm3 O particles per mm3 130 particles per mm3 75 particles per mm3

Soon after taking an aspirin, a patient has absorbed 300 milligrams of the drug. If the amount of aspirin in the bloodstream decays exponentially, with half being removed every 2 hours, find, to the nearest 0.1 hour, the time it will take for the amount of aspirin in the bloodstream to decrease to 100 milligrams. hr

8.36 grams of a mystery substance of food with a molar mass of 149.36 g/mol is burned in a bomb calorimeter. The water in the bomb calorimeter absorbs 105,961 Joules from the burning of the substance. Calculate the heat of combustion of the mystery substance in kJ/mol. (Please input your answer as a negative number.) (DO NOT PUT UNITS IN YOUR ANSWER.) Assume that all of the heat lost by the substance is transferred to the water and no heat is lost to the surroundings.
