Aqueous solution containing 23g `HCOOH` is/are :

A

`46g " of "70% w//v " "HCOOH (d_("solution")=1.4 g//ml)`.

B

`50g " of "10M " " HCOOH (d_("solution")=1 g//ml)`.

C

`50g " of " 25% w//w " "HCOOH`.

D

`46g " of "5M " "HCOOH (d_("solution")=1g//ml)`

Text Solution

Verified by Experts

The correct Answer is:
A, B
`(A) (70)/(100xx1.4)xx46=23g`
`(B) (10xx46)/(1000)xx50=23g`
`(C ) (25)/(100)xx50=12.5g`
`(D) (5xx46)/(1000)xx46 = 10.58g`
