kadar x massa jenis x 10 Molaritas Mr Mr NaOH = 23 +16+1 - 40 g/mol 30 x 1.33 x 10 Molaritas = 40 = 9.975 M

Hubungan antara persen massa dan molaritas Secara matematis: Molaritas (M) = kadar x massa jenis x 10 Mr • Menghitung Mr NaOH Mr NaOH = Ar Na + Ar O+Ar H = 23 +16+1 = 40 g/mol • Menghitung Molaritas Molaritas (M) = kadar Xmassa jenis x 10 Mr 30x1,33 g/ml x 10 40 g/mol = 9,975 M
