24 g
700gram = 0.7 kilogram
To prepare 2L of a 5M solution, you should put in 4.6575grams of KMnO4. It is important to make sure that you add them in that order. K should be added first, then Mn.
The formula for potassium permanganate is KMnO4
Dissolve 1,65 g potassium permanganate for analysis in 1 L demineralized water.
acidicness number of kmno4
KMnO4.
The compound potassium permanganate has chemical formula KMnO4 Molecular mass of KMnO4 = 39.1 + 54.9 + 4(16.0) = 158.0 Mass of KMnO4 = amount of KMnO4 x Molecular mass of KMnO4 = 2.55 x 158.0 = 403g
Potassium Hydroxide is KOH and potassium permanganate is KMnO4.
tell me about the vlance of Mn in KMnO4
Formula: KMnO4
Number of moles= Mass/molar mass (g/mol) Hence Mass= mol × molar mass Mol=2.55 Molar mass of KMnO4= 39+55+(16×4)= 158g/mol Where K=39, Mn=55 and O =16 Hence Mass of KMnO4 in 2.55 mols of the compound= 2.55×158= 402.9g.
