Some Basic Concepts Of Chemistry Question 37

Question: 10 mL of 2 M NaOH solution is added to 200 mL of 0.5 M of NaOH solution. What is the final concentration?

Options:

A) 0.57 M

B) 5.7 M

C) 11.4M

D) 1.14M

Show Answer

Answer:

Correct Answer: A

Solution:

[a] From molarity equation $M_{1} V_{1} + M_{2} V_{2} = M V_{(t o t a l)}$ $2 \times \frac{10}{1000} + 0.5 \times \frac{200}{1000} = M \times \frac{210}{1000}$ $120 = M \times 210$ $M = \frac{120}{210} = 0.57 M$
