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.
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.
The molar mass for potassium iodide is 166,0028.
Potassium bromide is KBr, so by adding together their molar masses, we get 39+80=119gmol-1
% by mole. There are six elements in KMnO4 only one is K so 1/6 which is 16.67% % by mass. Molar weight of K 39grams/mole. Molar weight of KMNO4 154 grams/mole so 39/154 =25%
Since we know the mass and molar mass, we can just insert them into this equation: n = m / M where n is the number of moles, m is the mass and M is the molar mass. I will not do the calculation for you, you should make your homework yourself (the molar mass of potassium can be found in the periodic table) :)
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.
molar mass is 158.03 g/mol color is purple chemical formula is 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
KMnO4 is potassium permanganate.
The valency of potassium permanganate is +7.

I believe it is 174.2592, but I could be mistaken. I believe it is 174.2592, but I could be mistaken. KNO3 has a molar mass of 101.10303
