（09宿迁）2009年6月1日，国家《食品安全法》正式实施，在食品行业中“免
检”一词已成为历史，“凡食品必检、不合格不上市”成为最基本原则。某检测站对某品牌
奶粉进行检测。取该奶粉样品100g，使其中蛋白质中的氮元素完全转变成氨气，用50g溶
质质量分数为9.8%的稀硫酸恰好完全吸收【2NH3+H2SO4＝（NH4）2SO4】。计算并回答下列问题：
（1）产生氨气的质量。
（2）该奶粉中含氮元素的质量分数。
（3）奶粉中蛋白质含量的国家标准为：每100g奶粉中含蛋白质12g—25g。 蛋白质中氮元
素的平均质量分数为16%，则合格奶粉中氮元素的质量分数范围为 ；通过对比说明
上述检测的奶粉是否合格？
