Question

The volume of HCl, containing 73 g L^-1 , required to completely neutralise NaOH obtained by reacting 0.69 g of metallic sodium with water, is _____ mL. (Nearest Integer) 

(Given : molar Masses of Na, Cl, O, H are 23, 35.5, 16 and 1 g mol^-1 respectively)

Answer 1

Correct answer is 15

NaOH reacts with HCl 

No. of equivalent of NaOH = No. of equivalent of HCl

Volume of HCl = 15 ml.
