Answer:
follow me....the answer is 1.5
Explanation:
total amount (in litres) of the solution=2+3+1=6 L
now,(molarity = no. of moles/volume in litres)...so that,
-> 1.5= no. of moles of NaOH/2L -> n.moles NaOH=3
->2= no. of moles of NaOH/3L -> n.moles NaOH= 6
(water is the solvent so don't need to find its moles)
So that, Now, final molarity of the solution will be,
M = n.moles/V(L)
= 3+6/6
= 9/6
= 1.5
HENCE THE MOLARITY OF THE TOTAL SOLUTION WILL BE 1.5M.

Hola mate
Here is your answer -
total no. of moles = M1V1 + M2V2
= 1.5 * 2 + 3 * 2 = 9 moles
final volume = 2 + 3 + 1 = 6 litres
final molarity = total no. of moles / final volume
= 9 / 6 = 1.5 M
