Answer:
molarity = no. of moles/volume in litre
use this to find the total no. of moles
moles of solution A
0.1 = n x 1000/100
n = 0.01
moles of solution B
0.1 = n x 1000/200
0.1 = n x 5
n = 0.02
add n of both the solution = total n = 0.01 + 0.02
= 0.03moles
total volume = 100 + 200 = 300ml = 0.3litre
final molarity = 0.03/0.3 = 0.1M
thus the final molarity = 0.1M
