小明去风景区游玩的时,捡回了诺干块石灰石样品,他采用了一下的方法对样品中的碳酸钙的质量分数进行检测:

问题描述：

取这种石灰石样品6克,把40克稀盐酸分四次加入,测量过程所得数据见下表(已知石灰石样品中含有杂质不溶于水).
表:``加入稀盐酸的次序`加入稀盐酸的质量(克)`剩余固体的质量(克)
``````````1`````````````````10```````````````````4.0````````
``````````2`````````````````10```````````````````m```````````
``````````3`````````````````10```````````````````0.6``````
``````````4`````````````````10```````````````````0.6```````````
问题:
1)6克石灰石样品中的杂质含量
2)m的数值
3)样品中碳酸钙的质量分数
4)所用稀盐酸的质量分数

问题解答：

1. 0.6g
2. 2.0
3. 90%
4. 14.6%
