0.84g of metal carbonate reacts exactly with 40 ml of `N//2H_2SO_4` . The equivelent weight of the metal carbonate is

A

84g

B

64g

C

42g

D

38g

Text Solution

Verified by Experts

The correct Answer is:
c
Weight,W=0.84g
Volume,V=40ml,
Normality,`N=1/2N`
`N=1/2=(0.84)/(Eq.wt)xx1000/40`
Eq. Wt`=(0.84xx1000xx2)/(40)=42g`
