The maximum quantity of oxygen that dissolves in water at 0 degrees celcius is 14.7 ppm and at 25 degrees celcius, it is 8.70 ppm. Calculate the difference in the mass of oxygen that can be dissolved in a fish tank containing 75.0 kg of water at the two temperatures.

An aqueous solution of cesium chloride is prepared by dissolving 52.3 g cesium chloride in 60.0g of water at 25°C. The volume of this solution is 63.3 mL . What is the molality of the solution?

The names and chemical formulae of some chemical compounds are written in the first two columns of the table below. Each compound is soluble in water. Imagine that a few tenths of a mole of each compound is dissolved in a liter of water. Then, write down in the third column of the table the chemical formula of the major chemical species that will be present in this solution. For example, you know water itself will be present, so you can begin each list with the chemical formula for water (H,O). Note: "major" chemical species are those present in concentrations greater than 10 -9- mol/L. dlo major species present when dissolved in water compound formula glycerol C,H,O, isopropanol C,H,0 nickel(II) chloride NiCl,

A student dissolves 8.3 of phenol (CH,OH) in 325. mL of a solvent with a density of 1.12 g/mL. The student notices that the volume of the solvent does not change when the phenol dissolves in it. Calculate the molarity and molality of the student's solution. Be sure each of your answer entries has the correct number of significant digits. molarity x10 molality 미

A student dissolves 5.2g of ammonia NH3 in 450.mL of a solvent with a density of 1.05 g/mL. The student notices that the volume of the solvent does not change when the ammonia dissolves in it. Calculate the molarity and molality of the student's solution. Round both of your answers to 2 significant digits. molarity =   molality =
