13. (5 pts.) An ideal liquid solution was made by mixing 22.5 moles of solvent “A”...
2A) An engineer is using reverse osmosis (“RO”) to desalinate a tank of contaminated water that has a concentration of 0.269 M CaCl2 (strong electrolyte) at 21.00°C to form deionized water. Given that 1 atm = 14.7 psi, the pressure he/she needed to apply across the “RO” membrane should be: (a) 422 psi (b) 286 psi (c) 179 psi (d) 206 psi 2B) An ideal liquid solution was made by mixing 22.5 moles of solvent “A” with 52.2 moles of...
