1.	An aqueous sodium hydroxide solution contains, 80ppm NaOH. If one ml of the solution is mixed with 99 ml water, the molarity of the resultant solution is x xx10^(-5) what is x? (assume d=gm/cc)
Answer» SOLUTION :PPM = `(w_(1))/(w_(2))xx10^(6)=80` `M=(w_(1))/(40xx((w_(2))/(1000)))(because w_(2)=V_("SOLN (mL)"))` `=(w_(1))/(w_(2))XX(1000)/(40)=(80xx10^(-6)xx1000)/(40)=2xx10^(-3)M` `M_(1)V_(1)=M_(2)V_(2)` `1xx2xx10^(-3)=100xxM_(2)impliesM_(2)=2xx10^(-5)`
