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?
You did not describe the amount of potassium bicarbonate amount in grams in your question. But if you are about 1 gram of potassium bicarbonate it will be 0.0099 moles in one gram of potassium bicarbonate. 0.0199 moles in 2 grams of potassium bicarbonate.
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?
First write a balanced chemical equation: 2K + Br2 ---> 2KBR Find the limiting reactant by using the moles of each element and determining which one gives you the smallest number of moles of potassium bromide. 2.92 mol K (2 mol KBr/2 mol K)= 2.92 mol KBr 1.78 mol Br2 (2 mol KBR/1 mol Br2)=3.56 mol KBr potassium is your limiting reactant so the max. number of moles of KBr that can be produced is 2.92 mol of KBr
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 potassium chlorate must be used to produce 6 moles of oxygen gas?
We need 3 moles of potassium perchlorate.
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 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?
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
