濃度指某物質在總量中所占的分量。

常用的濃度表示法有: 次數

質量百分濃度度=(溶質質量(g)/溶液質量(g))×100%=溶質質量(g)/(溶質質量(g)+溶劑質量(g))×100%
體積百分濃度=(溶質體積(mL)/溶液體積(mL))×100%=溶質體積(mL)/(溶質體積(mL)+溶劑體積(mL))×100%
百萬分濃度=溶質的質量(mg)/溶液的質量(kg)
質量莫耳濃度=溶質摩爾數(mol)/溶劑質量(kg)
1 m = 1 mol/kg
體積摩爾濃度=溶質摩爾數(mol)/溶液體積(L) 1 M = 1 mol/L
公式:c(溶液摩爾數的濃度mol/L)=n(溶質g)/v(溶液ml)
  • 質量濃度(m/V):指每單位體積的溶液中,溶質的質量。
