Comprehension # 1
Potash is any potassium mineral that is used for its potassium content. Most of the potash produced in the United States goes into fertilizer. The major sources of potash are potassium choride `(KCI)` and potassium sulphate `(K_(2)SO_(4))`. Potash production is often reported as the potassium oxide `(K_(2)O)` equivalent or the amount of `K_(2)O` that could be made from a given mineral. `KCI` cost `Rs 50 per kg`
For what price must `K_(2)SO_(4)` be sold in order to supply the same amount of potassium as in `KCI` ?

A

`"Rs". 58.40 kg^(-1)`

B

`"Rs". 50.00 kg^(-1)`

C

`"Rs". 42.82 kg^(-1)`

D

`"Rs". 25.00 kg^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
C
`"the price of" K_(2)SO_(4)`
`=(50)/(174)xx74.5xx2 implies Rs. `42.82 kg^(-1)`
