Prepared Kool-Aid is composed of 3 packages of Kool-Aid powder (5.0 g/package), 1.50 cups (300 g) of sugar (sucrose, C₁₂H₂₂O₁₁), and 1.00 gallon of water (approximately 3.79 kg H₂O). Assume the molecular weight of Kool-Aid powder is 230 g/gmol.

Calculate the mass fraction of sucrose, Kool-Aid powder, and water in the prepared Kool-Aid mixture.

Calculate the mole fraction of sucrose, Kool-Aid powder, and water in the prepared Kool-Aid mixture.

The air oven method was used to determine the moisture content of soft white wheat (U.S. produces about 7 million metric tons primarily in the Pacific Northwest according to U.S. Wheat Associates (2023)). It is used in bakery products that require lighter and flakier textures such pastries, cakes, and flatbreads. To determine the moisture content, 15.100 g of wheat was placed in a small aluminum dish (mass of 4.202 g) and then dried in an air oven at 130C for 19 h to evaporate all water. After drying, the mass of the dish plus dried wheat sample was measured and determined to be 17.943 g. Calculate the moisture content on a %db and %wb.
