What is the molar concentration of all ions present in a solution prepared by mixing the following? Assume that volumes of the solutions are additive, and neglect H+ and OH- from water. 80.0 mL of 0.65 M MgCl2 and 80.0 mL of 0.25 M Ba(OH)2. [Mg2+] = ? M [Ba2+] = ? M [Cl-] = ? M [OH-] ? M Please help me, I have no idea what to do! * the "M" means molarity

Answer:
since you have 80 ml and 80 ml the soltions mutually dilute each other by a factor of 2 Mg+ is0.33 M Cl- is divide by 2 then mult by 2 so 0.65M Ba+2 is 0.13 molar OH- is 0.25 M
