理化

1.體積莫耳濃度=溶質莫耳數/溶液體積（公升）
2.溶質莫耳數=溶質質量/溶質分子量=溶質粒子數目/6x10的23次方=體積莫耳濃度x溶液體積
3.稀釋前莫耳濃度x稀釋前溶液體積=稀釋後莫耳濃度x稀釋後溶液體積
4.稀釋後莫耳濃度=稀釋前莫耳濃度x（稀釋前溶液體積/稀釋後溶液體積）
5.任何水溶液在25°C時，$\left[H^{+}\right]\times \left[OH^{-}\right]=10^{-14}\times M^{2}$。
6.酸鹼中和公式 氫離子莫耳濃度=氫氧根莫耳濃度 =>酸性溶液莫耳數x酸性溶液化學式之氫離子個數=鹼性溶液莫耳數x鹼性溶液化學式之氫氧根個數

酸性溶液莫耳數=酸性溶液質量/酸性溶液分子量=酸性溶液粒子數目/6x10的23次方=酸性溶液體積莫耳濃度x酸性溶液體積

鹼性溶液莫耳數=鹼性溶液質量/鹼性溶液分子量=鹼性溶液粒子數目/6x10的23次方=鹼性溶液體積莫耳濃度x鹼性溶液體積

因此酸鹼中和總共16個公式
7.體積莫耳濃度=（重量百分濃度x溶液密度x1000）/溶質分子量
