What mass of `HNO_3` is required to make llitre of 2N solution to be used as an oxidizing agent in the reaction ?
`3Cu + 8HNO_3 rarr 3Cu(NO_3)_(2)+2NO+4H_2O`

A

63 g

B

21 g

C

42 g

D

84 g

Text Solution

Verified by Experts

The correct Answer is:
C
`N=W/(ExxV(L)),63/3`
`2=W/(63/3xx1),overset(+3^(-))(HNO_3)rarroverset(+2)(NO)`
w = 21 ` xx` 2 = 42 g
