Solution: 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 ...

Jan 31, 2014 · A solution is made by dissolving 25g of NaCl in enough water to make 1.00L of solution. Assume that the density of the solution is 1.00g/cm3. Calculate the mass percent, molarity, molality, and mole fraction of NaCl. A solution of phosphoric acid was made by dissolving 10.0g H3PO4 in 100.0mL water. The resulting volume was 104mL.

25 ml of 0.5% solution of drug X (NaCl equivalent = 0.31), how many mg of NaCl are needed to render the solution isotonic? Amount of drug in 25 ml = 0.5 X 25 X 1000 / 100 = 125 mg. NaCl equivalent = 125 X 0.31 = 38.75 mg. NaCl needed if used alone = 25 X 0.9 / 100 = 225 mg. NaCl needed to make the solution isotonic = 225 – 38.75 = 186.25 mg
