250 mL of 0.1 N solution of HCI contains

A

0.25 g mole of HCI

B

0.025 g mole of HCI

C

9.12 g moles of HCI

D

0.912 g moles of HCI

Text Solution

Verified by Experts

The correct Answer is:
B
Normality = molarirty ` xx ` charge on cation or anion
250 mL of 0.1 N HCI = 250 mL of 0.1 M HCI M
(0.1)/4` g mol
= 0.025 g moles of HCI
