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.

To calculate the grams of potassium permanganate in 2.20 moles, you would need to know the molar mass of potassium permanganate. The molar mass of potassium permanganate (KMnO4) is about 158.034 g/mol. So, 2.20 moles of KMnO4 is equal to 2.20 moles x 158.034 g/mol = 347.67 grams of potassium permanganate.

A gram is a unit of measurement, concerning how much mass, that is, how much of something there is. You would have to weight it (or mass it) on a scale to find out.
(158 g = 1 mole) --- molar mass of potassium permanganate. You also need to specify the volume to be made. For 1 liter just add 15.8 g in a volumetric flask to make 1000 ml (1 liter) of solution.
To prepare a 0.01 M solution of potassium permanganate (KMnO4), first calculate the amount needed by using the formula: mass (g) = molarity (mol/L) × volume (L) × molar mass (g/mol). The molar mass of KMnO4 is approximately 158.04 g/mol, so for 1 liter of solution, you would need 1.58 grams of KMnO4. Dissolve this amount in a small volume of distilled water, then transfer the solution to a 1-liter volumetric flask and dilute to the mark with distilled water. Mix thoroughly to ensure complete dissolution.
To find the mass of KMnO4 needed, you can use the formula: mass = molarity x volume x molar mass. First, calculate the moles of KMnO4 using moles = molarity x volume. Then, multiply the moles by the molar mass of KMnO4 to find the mass needed.
