Because the density does in fact represent a ratio, the mass of any size sample divided by the volume of that sample, gives the mass that 1.0 mL of the same sample would possess. Densities are usually determined and reported at 20 0C (around room temperature) because the volume of a sample, and hence the density, will often vary with temperature.

Calculate the molality of NaOH. (Assume the density of the solution is the same as the density of pure water.) Assume that you have 1 L of solution: Mass of water = mass of solution – mass of NaOH = 1000 g – (0.300 mol)(40 g/mol) = 1000 g – 12 g = 988 g. Molality = 0.300 mol/0.988 kg = 0.304 m

The density increases with either a temperature decrease or a salinity increase. Under normal ocean conditions, temperature fluctuations exert a greater influence on seawater density because the range of marine temperatures values is much greater (-2( C to 30( C) than the range of open-ocean salinity.

9) Participate in the CaCl2 solution density determination. Your instructor will oversee this part. 10) Collect the class’s CaCl2 results and plot the solution density vs CaCl2 concentration. 11) Include the class density measurements on the y-axis of your plot – use a different marker shape for each plastic.
