QUESTION 15 Which of the following aqueous solutions will have the LOWEST vapor pressure? , 0.20 m C6H12O6 O 0.20 m NaCl O 0.10 m CaCl2 â—‹ 0.40 m C2H3OH 0 0.20 in Na2SO4
please help me find the cation and anion nominal concentrations for columns 4 and 5. the original solutions used as sources of ions are all 0.20 M. I'd appreciate if you showed the process as well as the answers. thank you! no equilibrium constant was given. It says the dilution equation must be used to determine the the nominal concentrations.
