Correct option (d) 0.5 L of A + 1.5L of B
Explanation:
N1V1 + N2V2 = NV
Let vol. of A be x litres, therefore vol. of B is (2 – x) litres.
Using formula we get, 0.5 × x + (2 – x) × 0.1 = 0.2×2
⇒ 0.5x + 0.2 – 0.1x = 0.4
⇒ 0.4x = 0.2 ⇒ x = 0.5
Vol. of A is 0.5 litres, Vol. of B is 2 – 0.5 = 1.5 litres
