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
How many moles of Mn atoms are there in 16.1201 grams of KMnO4?
First start with what you know to find the total moles. Mn = 54.94g O = 16g 54.94g * 2 = 109.88g 16 * 3 = 48g Add these to get the weight of Mn2O3 which = 157.88 Divide 157.88 / 286 to get your total moles present, which = .552 Mols To find moles Mn, divide 54.94 by the total weight which is 157.88. This gives you your moles Mn, which is .348 mols. Since you have Mn2, multiply that number by 2 to get .695 mols Now you can divide Mol(Mn) by your total moles (.552) to get your moles Mn So .695 mol Mn2O3 / .552 mol Mn = 1.1 Mol Mn since 1.1 * 54.94 = 60 pct of the Molar Mass, this number makes sense since there is more Mn than O, the proportion seems correct. hope this helped! .
In manufacture of potassium permanganate by electrolysis of k2mno4 what should be the equivalent weight of kmno4 how much kmno4 will be produced by 96478 coulombs or one farady?
Equivalent weight of KMnO4 is equal with molar weight of KMnO4. The some is and for K2MnO4, K2MnO4 - e +OH- --------- KMnO4 + KOH In general, Equivalent weight = Molar weight / Number of electrons that take or give one molecule Equivalent weight of KMnO4 = Molar weight of KMnO4 / 1
Equation for benzene plus KMnO4?
Benzene does not react directly with potassium permanganate (KMnO4) under normal conditions. Benzene is a stable aromatic compound and does not undergo typical alkene or alkane reactions with oxidizing agents like KMnO4.
How many grams of potassium permanganate are in 2.20 moles?
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.
How many atom of oxygen are in 17.7g of potassium promangenate?
Assuming that the questioner meant to write "permanganate" instead of "promangenate", the answer may be found as follows: The formula of potassium permanganate is KMnO4, showing four atoms of oxygen per formula unit. The formula unit mass of KMnO4 is 158.03; therefore, 17.7 g of potassium permanganate contains [4(17.7)/158.03](Avogadro's Number) or 2.70 X 1023 atoms of oxygen, to the justified number of significant digits.
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).
Why does alkene reacts kmno4?
Alkenes react with potassium permanganate (KMnO4) through a process called oxidative cleavage, where the double bond is broken and oxygen atoms are added to the carbon atoms. This reaction results in the formation of diols (glycols) or ketones and carboxylic acids, depending on the conditions and the structure of the alkene.
Chemical symbol for permanganate?
The formula for potassium permanganate is KMnO4
Why benzene cannot decolonize KMnO4?
Benzene is a stable aromatic compound that does not readily undergo oxidation by potassium permanganate (KMnO4) due to the lack of reactive functional groups. Phenol or other compounds with labile hydrogen atoms are more susceptible to oxidation by KMnO4. Benzene's stable ring structure prevents it from being easily oxidized by KMnO4.
What is the formula for kmno4?
The chemical formula for potassium permanganate is KMnO4. It consists of one potassium (K) atom, one manganese (Mn) atom, and four oxygen (O) atoms.
What are the elements of KMnO4?
K: potassium Mn: manganese O: oxygen
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 structure of KMnO4 and how does it contribute to its chemical properties?
The structure of KMnO4 consists of one potassium (K) atom, one manganese (Mn) atom, and four oxygen (O) atoms. The manganese atom is in the center, surrounded by the oxygen atoms in a tetrahedral arrangement. This structure gives KMnO4 its strong oxidizing properties, as the manganese atom can easily gain or lose electrons, making it a powerful oxidizing agent in chemical reactions.
