The concentrations of the solutes in 150 ml of solution were 4% (w/v) and 10% (w/w), respectively. To complete the experiment performed by the student, calculate for the following: A. Mole fraction of the solute with the higher number of moles, B. Molarity of the solution if it contains ONLY the solute with the higher number of moles, C. Molality of the solution that you have computed in letter B, and D. Normality of the solution that you have computed in letter B.
- The average concentration of chloride ion in seawater is 19.353g Cl-/kg. The world health organization recommends that the concentration of Cl- ions in drinking water not exceed 250ppm. How many times as much chloride ion is there in seawater than in maximum concentration allowed in drinking water?In a biology laboratory, the teacher provided the each student group with two long bones (chicken) without the flesh. Following teacher's guidance, one of the long bone was placed in a beaker containing vinegar (7% acetic acid), a weak acid and let it sit for 3 days at 370 C in an incubator. The other long bone was left in beaker containing distilled water and placed in the same incubator. The students were very curious - on the 4th day, they used gloves and removed the bones from respective jars with utmost care. The teacher asked them to write their observations (what happened) and the explanation (why did it happen) in the lab notebook in view of the structure-function relationship of bone. Assuming we are doing this lab activity. describe the observation in the vinegar treated long bone compared to the control set and explain what actually happened to justify observationSuppose that in the reaction 2O3 → 3O2, a closed system initially contains 5.80 mol O2 and 6.20 mol O3.
