Potassium permanganate = KMnO4
Molar mass of KMnO4
K = 1 * 39.10 g = 39.10 g
Mn = 1 * 54.94 g = 54.94 g
O = 4 * 16.00 g = 64.00 g
Total = 158.04 g/mol
17.34 mol KMnO4 * (158.04 g/1 mol KMnO4) = 2740.41 g KMnO4
Convert the grams to kilograms. 1 kg = 1000 g
2740.41 g * (1 kg/1000 g) = 2.74041 kg
Therefore, 17.34 moles of potassium permanganate is equal to about 2.74 kilograms.

How many grams of potasium carbonate are in 1.5 moles of this substance?
1,5 moles of potassium carbonate have 276,41 g.
How many moles of iodine are needed to react with 5 moles of potassium to create potassium iodide?
Since molecules of potassium contain only single potassium atoms, molecules of iodine contain two atoms, and moles of potassium iodide contain one atom of each element, 2.5 moles of iodine are needed to react completely with 5 moles of potassium.
The formula potassium dichromate is K2Cr2O7. How many grams of oxygen will be in 2 moles of potassium dichromate?
In one mole of potassium dichromate, there seven moles of oxygen. This means in two moles of K2Cr2O7, there are 14 moles of O, or 7 Moles of O2, which equals 224 grams.
How many moles of KMnO4 are present in 75.0 mL of a 0.0950 M solution?
Molarity = moles of solute/Liters of solution ( 75.0 ml = 0.075 Liters ) Algebraically manipulate, moles of solute = Liters of solution * Molarity Moles KMnO4 = (0.075 Liters)(0.0950 M) = 7.13 X 10 -3 moles KMnO4 ------------------------------------
How many moles ok potassium are present in 343 mL of a 1.27 M solution of potassium phosphate?
The amount of potassium phosphate in the solution is 1.27 M * 0.343 L = 0.43561 moles.The chemical formula of potassium phosphate is K3PO4, so there is three times as many moles of potassium as there are moles of potassium phoshate in the molecule:0.43561 * 3 = 1.30683Answer: 1.31 moles
How many grams of potassium permanganate are in 2.20 moles?
This mass is 347,67 for KMnO4.
Can you dissolve .35 moles of Potassium Permanganate (KMnO4) into 500 mL of water?
The solubility of potassium permanganate in water at 2o 0C is 64 g/l (or 32 g/0,5 L).The molar mass of KMnO4 is 158,034 g and 0,35 moles KMnO4 is equal to 55,312 g.So it is not possible to dissolve o,35 moles KMnO4 in 0,5 L.
How many grams of potasium carbonate are in 1.5 moles of this substance?
1,5 moles of potassium carbonate have 276,41 g.
How many grams of potassium permanganate KMnO4 are in 2.55 moles?
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
What is the molality of a substance?
Molality is the number of moles of a solute divided by the weight of the solvent in kilograms.
What is the number of oxygen atoms in 90 g of potassium permanganate?
In order to find the actual number of Oxygen atoms in that substance, you must first find the molar mass of that substance by adding the atomic masses of all the atoms which make up that compound. Then, divide the mass of the substance you have by that molar mass. After that, multiply that amount by how many Oxygen atoms are in a molecule of the substance to find how many moles of oxygen you have. Then finally, multiply the number of moles of Oxygen by Avogadro's number (6.022*10^23).
