若设金属元素R的原子量为M，化合价为十n价，金属质量为X克，生成氨气的质量为y克。则：化简后计算通式：由计算通式可以得出以下二条计算规律：1．等质量的各金属与足量的某酸区应，产生氢气的质量之比签属元素化合价之比，且生氢气的质量之比=金属元素原子量之比，且比值中数 If the atomic weight of the metal element R is M, the valence is 10 n, the metal mass is Xg, and the mass of generated ammonia is yg. Then: Calculate the general formula after simplification: From the calculation of the formula, the following two calculation rules can be obtained: 1. Equal mass of each metal and a sufficient amount of acid area should be produced, the ratio of the quality of hydrogen produced is the ratio of the elemental valences, and the ratio of the mass of hydrogen gas = the atomic ratio of the metal element, and the ratio of the number of
