190.How many grams of barium sulphate are obtained when 26 g of barium chloride reacts with enough sulphuric acid? (Atomic mass of Ba = 137).
The balanced chemical equation representing the reaction is: BaCl2 + H2SO4 BaSO4 + 2HCl 1 mole 1 mole 137 + (2 x 35.5) 137 + 32 + (4 x 16) 208 g 233 g 26 g ? Stoichiometry indicates that 208 g BaCl2 gives 233 g BaSO4
