25. A meal replacement product was formulated to contain 380 mg Na per serving. If NaCl was used to achieve the intended Na level, and if this NaCl contained 100 ppm iodine, calculate the micrograms (to the nearest microgram) of iodine per serving in the finished product. Show your work.
26. An evaporator is used to concentrate cane sugar solutions. A feed of 10,000 kg/d of a solution containing 38% (wt %) sugar is evaporated producing a 74% (wt %) solution. Calculate the weight of solution produced and the amount of water removed. Show your work.
28. Determine the conversion factor to SI units:
a. an energy value of 1.7 Btu to kJ.
b. a pressure value of 14.69 psig (pounds per square inch [gauge] to kPa. Note: psia (pounds per square inch [absolute]) = psig + 14.69 (1 atm);
