1.	An inorganic compound contained 24.75% (w/w)potassium and 34.75% (w/w) manganeseand some other common element. Give theempirical formula of the compound (K 39u,Mn = 59u)
Answer» <p>let the mass of compound be 100gnow % potassium = 24.75 , so mass = 24.75 Then moles of potassium = 24.75/39 = 0.63 </p><p>and similarly moles of manganese = 34.75/59 = 0.58 </p><p>so, Moles of K and Mn are almost same .</p><p>=> emperical formula will be KMnX </p><p>where X => other common elements.</p>
