What is the percent composition of potassium in potassium iodide Kl?
The percent composition of potassium in potassium iodide (KI) is 58.5%. This is calculated by dividing the atomic mass of potassium by the molar mass of KI and multiplying by 100.
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
How many moles of potassium iodide are there in 50 grams?
For this you need the atomic (molecular) mass of KCl. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. KCl= 74.6 grams50.0 grams KCl / (74.6 grams) = .670 moles KCl
Why is potassium iodide used in iodometric titrations instead of sodium iodide?
I would guess that this is so because of potassium's mass, being much more than, sodium's molar mass per ion. So can sodium iodide be used instead of potassium iodide? Perhaps, but maybe not to the same level effectiveness. Potassium molecules have been known to dissolve better than sodium molecules. One example is Potassium Chloride and Sodium Chloride thanks
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 percentage of iodine in potassium iodide?
The percentage of iodine in potassium iodide can be calculated using the formula: (molar mass of iodine / molar mass of potassium iodide) x 100. The molar mass of iodine is approximately 126.9 g/mol, and the molar mass of potassium iodide is approximately 166 g/mol. Therefore, the percentage of iodine in potassium iodide is (126.9 / 166) x 100 = 76.5%.

What is the molar mass of KI?
The gram formula mass for KI or potassium iodide is 166.0027 grams per mole. You find this mass by multiplying the atomic masses of potassium and iodine by the number of atoms given for each in the formula, and then adding these two results.

What is the molar mass of tetramethylammonium iodide?
The molar mass of tetramethylammonium iodide is approximately 220.09 g/mol.
What is the molar mass potassium?
The molar mass of the element potassium is 39 g/mol.
What compounds has the highest molar mass sodium iodide sodium bromide sodium chloride lithium bromide lithium fluoride?
Sodium iodide has the highest molar mass among the compounds listed, with a molar mass of 149.89 g/mol. Sodium bromide has a molar mass of 102.89 g/mol, sodium chloride has a molar mass of 58.44 g/mol, lithium bromide has a molar mass of 86.85 g/mol, and lithium fluoride has a molar mass of 25.94 g/mol.

What is the percent composition of calcium iodide?
Calcium iodide has the chemical formula CaI2. To find the percent composition, calculate the molar mass of CaI2, then find the molar mass contributed by each element (calcium and iodine). Finally, divide the molar mass contributed by each element by the total molar mass of CaI2 and multiply by 100 to get the percent composition.
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
