In a square container, a lab technician carefully pours vinegar 1.049g/mL and palm oil 0.876g/mL The container and the liquids are then cooled to 0°C. A block of ice 0.917g/mL is then placed floating at the interface, as shown in the figure below. Determine the percentage of ice that will be submerged in vinegar, disregarding any melting or dissolution.

A 6-kg block of copper at 300 °C is submerged in 0.08 m3 of water at 0 °C contained in an insulated tank. Estimate the final equilibrium temperature. Conservation of energy requires that the energy lost by the copper block is gained by the water. Units are in Celsius.

A mixing tank contains 125 kg corn liquor and 45 kg beet molasses; water is then added to produce a diluted sugar mixture containing 2% (w/w) invert sugars. Corn liquor contains 3% invert sugars and 50% water, the rest can be considered solids. Beet molasses contains 50% sucrose, 1% invert sugars, and 18% water; the remainder is solids. (a) How much water is required? (b) What is the concentration of sucrose in the final mixture?

Exhaust gas from an automobile contains air and 10-4 mole fractions of NO in air at 25 degC and 1.2 atm. Express this concentration as a mass concentration (kg/m3). Remember  that the MW of NO is 30 g/mol
