Alum Molar Mass (With Calculations) - Knords Learning
Potassium alum dodecahydrate occurs in nature as a sulfate mineral called alum-(K), typically as encrustations on rocks in areas of weathering and oxidation of sulfide minerals and potassium-bearing minerals. In the past, potassium alum has been obtained from alunite (KAl(SO 4) 2·2Al(OH) 3), mined from sulfur-containing volcanic sediments. Alunite is an associate and likely potassium and aluminiu… WebScience Chemistry Write the empirical formula for the hydrated KAl (SO4)2, based on moles of anhydrous KSI (SO4)2= 0.046 mol molar mass of H2O= 18g/ mol moles of … chemstar sds sheets
