reacting weight

例句：

1. 1. The reacting weight of the chemical reaction is a crucial factor in determining its efficiency.
   化学反应的反应重量是决定其效率的关键因素。
2. 2. During the reaction, the reacting weight of the reactants increases and decreases accordingly.
   在反应过程中，反应物的参与量会增加或减少。
3. 3. The reacting weight of the reactants is calculated using the formula: W = m(M + M_R) / 2, where W is the reacting weight, m is the mass of the reactants, M is the molecular weight of the reactants, and M_R is the molar mass of the reactants.
   反应物的反应重量通过公式计算得出：W = m(M + M_R) / 2，其中W是反应物的反应重量，m是反应物的质量，M是反应物分子量，M_R是反应物的摩尔质量。
