What is the molar mass for potassium iodide?
The molar mass for potassium iodide is 166,0028.
What is the molar mass of potassium bromide?
Potassium bromide is KBr, so by adding together their molar masses, we get 39+80=119gmol-1
Find the number of moles in 25.0 grams of potassium?
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) :)
What is the molar mass of potassium sorbate?
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
What is the mass of 1.474 mol of potassium sulfide?
To find the mass of 1.474 mol of potassium sulfide, you need to multiply the number of moles by the molar mass of potassium sulfide. The molar mass of potassium sulfide (K2S) is approximately 110.26 g/mol. Therefore, the mass of 1.474 mol of potassium sulfide is about 162.62 grams.
What is the molar mass of KOH?
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
How much does 35.1 moles of potassium weigh?
The molar mass of potassium (K) is approximately 39.1 g/mol. Using this molar mass, we can calculate the weight of 35.1 moles of potassium by multiplying the molar mass by the number of moles. Therefore, 35.1 moles of potassium would weigh approximately 1371.41 grams.
How much does potassium nitrate weigh?
The molar mass of potassium nitrate is 101,1032 g.
Calculate the molar mass for K2S?
The molar mass of K2S (potassium sulfide) can be calculated by adding the atomic masses of potassium (K) and sulfur (S). The atomic mass of potassium is approximately 39.1 g/mol and the atomic mass of sulfur is approximately 32.1 g/mol. Therefore, the molar mass of K2S is approximately 2(39.1) + 32.1 = 110.3 g/mol.
Does KCI have the molar mass of 120.37?
No, KCI (potassium chloride) has a molar mass of approximately 74.55 g/mol.
What are the formula molar mass and color of potassium permanganate?
molar mass is 158.03 g/mol color is purple chemical formula is KMnO4
How many grams of potassium are in 27.8 g of K2CrO7?
To find the grams of potassium in K2CrO7, first determine its molar mass. Potassium (K) has a molar mass of 39.10 g/mol, and K2CrO7 has two potassium atoms, so (39.10 g/mol) * 2 = 78.20 g/mol. Then, divide the mass of K2CrO7 by its molar mass to get the grams of potassium: (27.8 g) / (294.19 g/mol) ≈ 9.45 g of potassium.
