The formula for potassium bisulfate is KHSO4. Using the atomic weights on the Periodic Table for each element, the molar mass of KHSO4 is 136.1688g/mol.
Therefore, 1 mol KHSO4 = 136.1688g
282.1g KHSO4 x (1mol KHSO4/136.1688g KHSO4)= 2.027 mol KHSO4
12 g of potassium is equivalent to 0,307 moles.
34,7 moles of potassium 1 356,7 g.
We need 3 moles of potassium perchlorate.
Four moles of potassium chlorate are needed.
The answer is 1 mole potassium chlorate.
Since molecules of potassium contain only single potassium atoms, molecules of iodine contain two atoms, and moles of potassium iodide contain one atom of each element, 2.5 moles of iodine are needed to react completely with 5 moles of potassium.
The balanced equation for this reaction is: 2K3PO4 + 3Al(NO3)3 -> 6KNO3 + AlPO4. This indicates that 2 moles of potassium phosphate react with 2 moles of aluminum nitrate to produce 6 moles of potassium nitrate.
25,3 moles of potassium sulfate hva a mass of 4,4409 kg.
The amount of potassium phosphate in the solution is 1.27 M * 0.343 L = 0.43561 moles.The chemical formula of potassium phosphate is K3PO4, so there is three times as many moles of potassium as there are moles of potassium phoshate in the molecule:0.43561 * 3 = 1.30683Answer: 1.31 moles
12 moles KClO3 (3 moles O/1 mole KClO3) = 36 moles of oxygen.
45/94.2 is 0.4777 moles
To produce potassium nitride (K₃N), the balanced chemical equation is 6 K + N₂ → 2 K₃N. This indicates that 6 moles of potassium are required to produce 2 moles of potassium nitride. Therefore, to produce 2.0 moles of K₃N, you would need 6 moles of potassium.
