酢酸のモル濃度｜モル濃度計算ツールと濃度早見表
無色透明で刺激臭のある液体。代表的な弱酸。本ページは、酢酸の w/w% からモル濃度を計算するツールです。
酢酸のモル濃度計算
- モル濃度
- 0 mol/L
計算方法
液体試薬のモル濃度は、密度、質量パーセント濃度（w/w%）、分子量から次の式で求められます。
モル濃度 (mol/L) = 密度 (g/mL) × 濃度 (w/w%) × 10 / 分子量 (g/mol)
酢酸の濃度・密度・モル濃度の早見表（20℃）
酢酸（CH₃COOH 水溶液）の代表的な濃度（w/w%）と、20℃における密度 / 比重、対応するモル濃度の対応表です。製品により多少の差があるため、正確な値は試薬ラベルや SDS を確認してください。
