$10 mL$ of $2 (M) NaOH$ solution is added to $200 mL$ of $0.5$ $(M)$ of $NaOH$ solution. What is the final concentration ?

Options:

Answer:

Solution:

From molarity equation $M_{1} V_{1} + M_{2} V_{2} = MV_{(total)} 2 \times \frac{10}{1000} + 0.5 \times \frac{200}{1000} = M \times \frac{210}{1000} 120 = M \times 210 M = \frac{120}{210} = 0.57 M$
