Mg (OH)2 = 1.05 * 1 = 1.05 moles. NaCl = 1.05 * 2 = 2.10 moles. You now know the number of moles of each substance needed in a theoretical perfect reaction. If you want to know the number of grams needed of each substance, you can multiply by the molar mass of each substance: NaOH = 2.10 mol * 39.997 g/mol = 83.9937g.

Learning Objectives. Use stoichiometry to calculate the amount (in moles or grams) of a particular substance produced or used in a chemical reaction. Use stoichiometry to determine molecular formulas. A balanced chemical equation provides a great deal of information in a very succinct format. Chemical formulas provide the identities of the ...
19 Φεβ 2022 · How many NH 3 molecules are produced by the reaction of 4.0 mol of Ca (OH) 2 according to the following equation: (NH 4) 2SO 4 + Ca(OH) 2 → 2NH 3 + CaSO 4 + 2H 2O. Answer. These examples illustrate the ease with which the amounts of substances involved in a chemical reaction of known stoichiometry may be related.
In order to balance C on both sides we: Multiply coefficient for CO 2 by 2. 2 CO 2 + 1 Mg (OH) 2 = 1 Mg (HCO 3) 2. Mg is balanced: 1 atom in reagents and 1 atom in products. H is balanced: 2 atoms in reagents and 2 atoms in products. O is balanced: 6 atoms in reagents and 6 atoms in products.
14 Αυγ 2020 · To illustrate this idea, consider the production of ammonia by reaction of hydrogen and nitrogen: N2(g) + 3H2(g) → 2NH3(g) (4.2.3) This equation shows that ammonia molecules are produced from hydrogen molecules in a 2:3 ratio, and stoichiometric factors may be derived using any amount (number) unit:
Calculate the maximum mass of carbon dioxide that can be produced. (Relative formula masses: CaCO 3 = 100.1, CO 2 = 44.0)
