The amount of solid Mg ( OH ) 2 that exactly reacts with 200. mL of a 0.10 M HCl is to be calculated. Concept introduction: Stoichiometry of a chemical species involved in a chemical reaction represents the amount of chemical species involved in the chemical reaction. The stoichiometry of a chemical species helps in calculating the expected mass of reactant and product. Stoichiometry of a chemical species is also represented in number of moles. The number of moles of a substance is given as, n = m M Where, • m represents the mass of the substance. • M represents the molar mass of the substance.
