(Al)26.98+(K)39.10+2(S)32.07+8(O)16.00+24(H)1.008+12(O)16.00= 474.4 g/mole
Molar mass = 258.21 g/mol
Molecular formula = KAl(SO4)2
what is equivalent weight of potash alum
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
Alum crystals turn into a solid mass of anhydrous alum
The molar mass of potassium chloride is 74,5513.
molar mass is the mass of one mole of a substance. A mole is an amount, refers to Avogadros number which is 6.022 x 1023. a mole of atoms is that many atoms. therefore the molar mass of potassium hydroxide KOH is the mass of that many molecules of KOH. On the periodic table the mass number for each element is molar, so all you need to do is add together the molar mass of each element in the compound. Molar mass of potassium (K) is 39 Molar mass of oxygen (O) is 16 Molar mass of hydrogen (H) is 1 There is one of each of these elements in a molecule of potassium hydroxide therefore the molar mass = 39 + 16 + 1 = 56
The molar mass for potassium iodide is 166,0028.
The molar mass of the element potassium is 39 g/mol.
Potassium bromide is KBr, so by adding together their molar masses, we get 39+80=119gmol-1
Alum crystals turn into a solid mass of anhydrous alum
The molar mass of potassium chloride is 74,5513.
The molar mass of potassium nitrate is 101,1032 g.
molar mass is 158.03 g/mol color is purple chemical formula is KMnO4

The molar mass of potassium sulfide is approximately 110 g/mol.
Molar mass of KNO3 is 101gmol-1. This is a neutral compound.
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
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) :)
