2.5 L of 1 M NaOH solution is mixed with another 3 L solution of 0.5 M NaOH solution Then the molarity of the resulting solution is....

A

0.560 M

B

1.0 M

C

0.73 M

D

0.50 M

Text Solution

Verified by Experts

The correct Answer is:
C
Molarity of mixture,
`=(M_(1)V_(1)+M_(2)V_(2))/(V_(1)+V_(2))=(1xx2.5+0.5xx3)/(5.5)`
`=0.727~~0.73M`
