Two aqueous NaCl solutions of equal volume and concentration were kept in flasks and held at different temperatures. The two solutions were combined in a larger flask. ... that the density of H 2 O is 1.00 g/mL, and that the specific heat capacity of H 2 O is about 4.2 J/g⋅°C. Based on this information, estimate how much heat was released ...

What is the relationship between temperature and the molarity of a saturated NaCl solution? Phosphoric acid is usually obtained as an 87.0% (by mass) phosphoric acid solution. If it is 13.0 M, what is the density of this solution? What is its molality? An aqueous solution of hydrofluoric acid is 30.0% HF, by mass, and has a density of 1.101 g cm-3.

The density of the seawater is 1023kg/m3 at 25 C., so the mass flow rate of the input water is: 10.64kg/s. Osmotic pressure . C = [NaCl] = ; CT (Na+, Cl-) = 1.18M. During continuous operation, salt concentration will increase to 1.18/0.2 = 5.9 M (Nobody had realized the salt concentration before the membrane is the same as the brine reject)
