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 ?
