How many moles of potassium are contained in 449 g of potassium?
To determine the number of moles of potassium in 449 g, you need to divide the mass (449 g) by the molar mass of potassium (39.1 g/mol). This calculation would give you the number of moles of potassium in 449 g.
Hoy many moles of potassium nitrate are produced when 2 moles of potassium phosphate react wth 2 moles of aluminum nitrate?
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.
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 moles of potassium bromide can be produced from the reaction of 2.92 moles of potassium with 1.78 moles of bromine gas?
1:2 mole ratio of potassium to bromine in the balanced chemical equation, so the limiting reactant is potassium since it produces fewer moles of product. 2.92 moles of potassium can produce 1.46 moles of potassium bromide.
He formula for potassium dichromate is KËÃCrËÃOËÈ How many grams of oxygen will be in 2 moles of potassium dichromate?
In 2 moles of potassium dichromate, there are 16 moles of oxygen atoms (from the two oxygen atoms in each formula unit). The molar mass of oxygen is 16 g/mol, so in 2 moles of potassium dichromate, there are 32 grams of oxygen.
How many moles in 449 g of potassium?
To find the number of moles in 449 g of potassium, divide the given mass by the molar mass of potassium. The molar mass of potassium (K) is approximately 39.10 g/mol. Therefore, 449 g divided by 39.10 g/mol is approximately 11.49 moles of potassium.
How many moles of potassium are contained in 449 g of potassium?
To determine the number of moles of potassium in 449 g, you need to divide the mass (449 g) by the molar mass of potassium (39.1 g/mol). This calculation would give you the number of moles of potassium in 449 g.
How many moles are in 12g of potassium?
12 g of potassium is equivalent to 0,307 moles.
How many grams are in 34.7 moles of potassium?
34,7 moles of potassium 1 356,7 g.
How many moles of potassium chlorate must be used to produce 6 moles if oxygen gas?
Four moles of potassium chlorate are needed.
How many moles potassium chlorate must be used to produce 6 moles of oxygen gas?
We need 3 moles of potassium perchlorate.
How many moles are contained in 22.23 g KBr-?
0.1868 moles
How many moles of potassium chlorate are needed to give 1.50 moles of oxygen?
The answer is 1 mole potassium chlorate.
How many moles of iodine are needed to react with 5 moles of potassium to create potassium iodide?
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.
How many grams of potassium sulfate are there in 25.3 moles?
25,3 moles of potassium sulfate hva a mass of 4,4409 kg.
Hoy many moles of potassium nitrate are produced when 2 moles of potassium phosphate react wth 2 moles of aluminum nitrate?
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.
How many moles ok potassium are present in 343 mL of a 1.27 M solution of potassium phosphate?
To find the moles of potassium in the solution, first calculate the moles of potassium phosphate using the formula Molarity (M) = moles of solute / volume of solution in liters. Then, consider that each mole of potassium phosphate contains 3 moles of potassium ions. Finally, convert the volume of the solution to liters by dividing by 1000.
