What is the number of milliequivalents of HCl in 50 mL of solution?

1. 5
2. 6
3. 10
4. 20

Correct answer: 10

Solution

Milliequivalents are calculated as normality × volume (in mL). Assuming the normality of HCl is 0.2 N (not provided but typical for such questions), milliequivalents = 0.2 × 50 = 10.
