Question

2.5 litre of 1M NaOH solution mixed with another 3 litre of 0.5M NaOH solution. Then find out molarity of resultant solution

Answer 1

Hey there,

Formula used will be = M1V1+M2V2
                                    -------------------- =final molarity
                                     total volume 
putting values 
                   
2.5x1 + 3x0.5
------------------- = Final Molarity
      5.5
                                    
Hence M = 0.727 moles/L
