2) to make 2 molecules of water (H 2 O)" can also be stated as "1 mole of O 2 will react with 2 moles of H 2 to form 2 moles of water". The same chemical fact, expressed in terms of masses, would be "32 g (1 mole) of oxygen will react with approximately 4.0304 g (2 moles of H
Mannheim: 2 NaCl + H 2 SO 4 → 2 HCl + Na 2 SO 4 Hargreaves: 4 NaCl + 2 SO 2 + O 2 + 2 H 2 O → 4 HCl + 2 Na 2 SO 4 The second major production of sodium sulfate are the processes where surplus sodium hydroxide is neutralised by sulfuric acid to obtain sulfate ( SO 2− 4 ) by using copper sulfate (CuSO 4 ) (as historically applied on a large ...
The mole is widely used in chemistry as a convenient way to express amounts of reactants and amounts of products of chemical reactions. For example, the chemical equation 2 H 2 + O 2 → 2 H 2 O can be interpreted to mean that for each 2 mol molecular hydrogen (H 2) and 1 mol molecular oxygen (O 2) that react, 2 mol of water (H 2 O) form.
m(NaCl) = 2 mol/L × 0.1 L × 58 g/mol = 11.6 g. To create the solution, 11.6 g NaCl is placed in a volumetric flask, dissolved in some water, then followed by the addition of more water until the total volume reaches 100 mL. The density of water is approximately 1000 g/L and its molar mass is 18.02 g/mol (or 1/18.02 = 0.055 mol/g). Therefore ...
