Question

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

Answer 1

2.5litre 1M NaOH solution is mixed with another 3 litre of 0.5M ...

thenThe molarity of resultant solution is equal to M1V1 + M2V2 / V1+ V2 = 2.5+1.5 / 5.5 = 4 / 5.5 = 0.7272M
