There are 0.151 moles of potassium permanganate in 250 grams.
So let us dig a little deeper
Potassium permanganate (KMnO4) is a strong oxidizing agent commonly used in industries such as chemical manufacturing, water treatment, and medicine. It is also used as a disinfectant and a bleaching agent in some hair and beauty products. The question at hand is how many moles are there in 250 grams of potassium permanganate.
Using the molar mass of KMnO4, which is 158.034 g/mol, we can calculate the number of moles in 250 grams.
To do this, we divide the mass (250 g) by the molar mass (158.034 g/mol):
250 g ÷ 158.034 g/mol = 1.581 mol
Therefore, there are 1.581 moles of KMnO4 in 250 grams.
A famous chemist once said, “Chemistry should contribute towards making the world less complex, not more.” – Roald Hoffmann
Interesting facts about potassium permanganate:
Potassium permanganate was first synthesized in 1659 by a British chemist named Henry Cavendish.
It has a bright purple color and can stain skin and clothing.
In its solid form, KMnO4 is a dark purple crystal.
It is not soluble in organic solvents but can dissolve in water to form a purple solution.
It is used to treat fish diseases in aquariums and ponds.
Potassium permanganate is also used in forensic science to detect fingerprints.
It can react with certain materials, such as glycerin and sugar, to create a fire.

0.16 moleThe problem gives us 25.0 grams. Step Two: You need to know the molar mass of the substance. The molar mass of KMnO4 is 158.034 grams/mole. The answer of 0.16 mole has been rounded off.
0.158 molesNumber of moles is defined as the ratio between given mass and molar mass.Given:Mass= 25.0 gramsTo find:Molar mass=?Molar mass of KMnO₄ = 158 g/mol[tex]\text{Number of moles}= \frac{\text{Given mass}}{\text{Molar mass}} \\\text{Number of moles}=\frac{25}{158} \\\text{Number of moles}=0.158 \text{ moles}[/tex]Thus, the number of moles of potassium permanganate, KMnO₄ is 0.158 moles.

How do you find the moles of KMnO4?
Mass = # moles x molar mass Molar mass of KMnO4 = 158.0 g/mole Mass of KMnO4 needed = 0.0025 mol x 158.0 g/mole = 0.395 g of KMnO4 So, weigh 0.395 g of KMnO4 and dissolve them in 250 ml volumetric flask.
What is the number of moles of potassium permanganate?
The reply will be: Number of moles is defined as the ratio between given mass and molar mass. Molar mass=? Thus, the number of moles of potassium permanganate, KMnO₄ is 0.158 moles.
How to calculate molar mass of a gas?
The molar mass of a gas is straightforward to measure, as equal volumes contain equal number of moles. You can calculate the molar mass of a molecule by summing the molar masses of the composing atoms with the help of the periodic table.
How do you calculate moles?
As an answer to this: To correctly estimate the number of moles, n, of a substance of a specific mass, m, (in grams), you need to follow the grams to moles formula: M is the molar mass of this material. The unit is typically g/mol. But wait, what actually is a mole? The mole is the SI unit of measurement for the amount of a substance.
What is a molar concentration?
Response to this: Molar concentration can be used to convert between the mass or moles of solute and the volume of the solution. In real life, we often encounter substances that are mixtures of different elements and compounds. One example of a mixture is the human body. Did you know that the human body is approximately 57\% 57% water by mass?
What is the number of moles of potassium permanganate?
The reply will be: Number of moles is defined as the ratio between given mass and molar mass. Molar mass=? Thus, the number of moles of potassium permanganate, KMnO₄ is 0.158 moles.
How do you convert 25 grams of potassium chlorate to moles?
change 25 grams of potassium chlorate to moles. calculate the gram molecular mass of potassium chlorate. Chlorate is Cl with 3 oxygens. ate = saturated. Chlorine has seven valance electrons when it is saturated six of these electrons are used by oxygen ( 2 electrons per oxygen) leaving only 1 electron. 25 122.4 = moles.
