How many grams of concentrated nitric acid solution should be used to prepare 250 mL of 2.0 M `HNO_(3)` ? The concentrated acid is `70%HNO_(3)`.

A

`45.0" g conc. HNO"_(3)`

B

`90.0" g conc. HNO"_(3)`

C

`70.0" conc. HNO"_(3)`

D

`54.0" g conc. HNO"_(3)`

Text Solution

Verified by Experts

The correct Answer is:
A
`(w)/(E)=NV`
`(w)/(6.3)=2xx(250)/(1000)`
`w=(63)/(2)=31.5g`
but `70%` solution
70 g is used the wt. of solution is 100 g
31.5 g is used the wt. of solution is ?
`(100)/(70)xx31.5=45g`
