2.5litre of 1 MNaOH solution is mixed with another 3litre of 0.5 MNaOH solution. Then find out molarity of resultant solution.
A
0.80 
B
1.0 
C
0.73 
D
0.50 
Text Solution
Verified by ExpertsThe correct answer is:
C
Molecular weight of NaOH 
2.5 litre of 1 MNaOH solution contain 
of NaOH
3litre of 0.5 MNaOH solution contain 
of NaOH
If these two solutions are mixed, the volume of the resultant solution 
litre.
5.5 litre of the resultant solution contain
40(2.5 
1.5) 
of NaOH
1litre of the resultant solution contain
of NaOH 
mole of NaOH
The molarity ofthe resultant solution
