Question

200 mL of 0.2 M KOH and 800 mL of 0.4 M NaOH are mixed with each other. Molarity of the resultant mixture is ----- M

Moderate

A

0.27
B

0.24
C

0.18
D

0.36

Solution

$M = \frac{V_{1} M_{2} + V_{2} M_{2}}{Total volume of the mixture}; M = \frac{200 (0.2) + 800 (0.4)}{1000}; M = 0.36 M;$
