A student wants to prepare 1.00 L of a 1.00 M solution of NaOH (molar mass 40.00 g/mol). If solid NaOH is available, how would the student prepare this solution? If 2.00 MNaOH is available, how would the student prepare the solution? To help insure three significant figures in the NaOH molarity, to how many significant figures should the volumes and mass be determined?
a. How many design variables must be specified in order to calculate the output stream compositions and flow rates? b. How would you optimize these variables if the objective of the separator was to maximize recovery of condensable components into ..
Monczka-Trent has two options: (1) its standard 2-day shipment or (2) a subcontractor who will team drive overnight with an effective delivery of 1 day. The extra driver costs $175. Handfields's holding cost is 35% annually for this kind of inventory..
Determine the minimum required numerical value of the dimension b of the posts in term of mm and
The thermal design of a heat exchanger to recover heat from a kerosene stream by transfer to a crude oil stream was carried out in. Make a preliminary mechanical design for this exchanger. Base your design on the specification obtained from the CA..

Stoichiometry of Ammonia Synthesis, Show that the maximum concentration of NH3 is obtained in an ammonia synthesis process when the ratio of nitrogen to hydrogen
Assume you have gas in a cylinder equipped with a piston. There are weights on the piston creating pressure down on the gas.
Consider 1 mole of ideal gas at 1 bar and 300 K, which of the following statements is true? The absolute entropy of the system is negative. Helium (m=4 amu) will have a larger entropy than argon (m=40 amu).
using the concept of a mass balance describe how environmental engineers and scientists model the carbon cycle in the
Using the data given in Appendix C (available online at booksite .Elsevier.com/Towler), calculate the gross and net calorific values of the gas. Give your answer in MJ/m3, at standard temperature and pressure.
Acetone of at least 95 mol% purity is wanted, and the aqueous effluent must not contain more than 1 mol% acetone. The feed will be a saturated liquid. Estimate the number of ideal stages required.
Develop the designed circuit using breadboard in the laboratory. Available thermal sensor can be used in the circuit. Discuss the effect of resistors on calibration of the sensor with specific emphasis on the sensitivity of the instrument.
