✔ 最佳答案
molarity = M, 是液體濃度
1M = 1mole/litre
mole 是重量
1mole = mass (g) of compound in 1 mole

2007-01-31 12:27:15 補充:
mole = mass (g) / molar mass (g)molar mass = mass (g) of compound in 1mole

2007-02-01 13:49:42 補充:
樓下位朋友, 應是1dm3=1000cm3 (而不是1dm=1000cm3)另外1L=1dm3=1000cm3
參考: 自己的化學知識

Molarity 是 mole 除 volume
volume 是 1dm, 1dm=1000cm3
