Question

3.15 gm of an acid is dissolved in water and makes the volume 500 ml. 20 ml of this
solution requires 20 ml of N/10 NaOH solution to neutralize. If acid is dibasic, calculate
its molar mass.​

Answer 1

Answer:

126 gm

Explanation:

initially find its molarity i.e.= 6.30/m

now N1V1=N2V2

Normality = n factor into molarity

2*6.30/m*20 = 20* 1/10

solve this and you will get m=126 gm
