Calculate the mass in 3.3 moles of potassium sulphide?
To calculate the mass of 3.3 moles of potassium sulfide, you would first determine the molar mass of K2S. The molar mass of potassium (K) is 39.1 g/mol and sulfur (S) is 32.1 g/mol. Therefore, the molar mass of K2S is 39.1*2 + 32.1 = 110.3 g/mol. Multiply this molar mass by 3.3 moles to find the mass.
What is the molar mass of krypton?
There are 39.0983 grams in one mole of K (potassium). a mole is a number. you cannot ask how many moles are in potassium. but you may ask how many moles of a certain substance are in potassium.
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%.
How many moles in potassium bicarbonate?
To calculate the number of moles of potassium bicarbonate, you need to know the mass of the compound. Potassium bicarbonate has a molar mass of approximately 100.12 g/mol. Divide the mass of the sample by the molar mass to calculate the moles.
How many grams of potassium permanganate are in 2.20 moles?
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.
What is the molar mass potassium?
The molar mass of the element potassium is 39 g/mol.
What is the molar mass for potassium iodide?
The molar mass of potassium iodide (KI) is approximately 166.0 grams per mole.
What is Constituent element of potassium sorbate?
Potassium sorbate is composed of potassium, which is inorganic, and sorbic acid, which is an organic compound. When potassium sorbate dissolves in water, it releases potassium ions and sorbate ions.
Is potassium sorbate ionic or covalent?
Potassium sorbate is ionic because it is formed from the ionic bonding between potassium, which is a metal and forms cations, and sorbate, which is an anion. This results in the transfer of electrons from potassium to sorbate, leading to the formation of an ionic compound.
What are the elements of potassium sulfate?
The chemical formula of potassium sorbate is C6H7O2K; potassium sorbate contain carbon, hudrogen oxygen and potassium.
What is the molar mass of potassium bromide?
The molar mass of potassium bromide (KBr) is approximately 119 g/mol. This can be calculated by adding the atomic masses of potassium (39.10 g/mol) and bromine (79.90 g/mol).
Chemical formula for potassium sorbate?
The chemical formula for potassium sorbate is C6H7KO2.
Find the number of moles in 25.0 grams of potassium?
To find the number of moles in 25.0 grams of potassium, you need to divide the given mass by the molar mass of potassium. The molar mass of potassium is approximately 39.1 g/mol, so 25.0 g divided by 39.1 g/mol is approximately 0.64 moles of potassium.
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.
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.
