What is the mass of 0.41 mol of the element potassium?
The molar mass of potassium (K) is approximately 39.10 g/mol. To find the mass of 0.41 mol of potassium, you would multiply the molar mass by the number of moles: 39.10 g/mol * 0.41 mol = 16.049 g. So, the mass of 0.41 mol of potassium is approximately 16.049 grams.
What is the atomic weight for the element potassium?
The standard of atomic weight 39.0983 +/- 0.0001 u
What is molecular mass of potassium in potassium chloride?
Since potassium chloride has the formula KCl and the mass of the lost electron from neutral potassium is negligible compared with the mass of the protons and neutrons in the potassium atom nucleus, the molecular mass of potassium in this compound is the same as the atomic mass of potassium, 39.098.
What is the molar mass of Kl(potassium iodide)?
The molar mass of potassium iodide (KI) can be calculated by adding the atomic masses of potassium (K) and iodine (I). The atomic mass of potassium is approximately 39.10 g/mol, and that of iodine is about 126.90 g/mol. Therefore, the molar mass of KI is approximately 166.00 g/mol.
Calculate the mass in grams of 2.60 mol of potassium chloride (KCl)?
To calculate the mass of 2.60 mol of potassium chloride (KCl), first determine its molar mass. The molar mass of KCl is approximately 74.55 g/mol (39.10 g/mol for K and 35.45 g/mol for Cl). Thus, the mass can be calculated using the formula: mass = moles × molar mass. Therefore, the mass of 2.60 mol of KCl is 2.60 mol × 74.55 g/mol = 193.83 grams.

What is the molar mass potassium?
The molar mass of the element potassium is 39 g/mol.
What is the mass of 0.41 mol of the element potassium?
The molar mass of potassium (K) is approximately 39.10 g/mol. To find the mass of 0.41 mol of potassium, you would multiply the molar mass by the number of moles: 39.10 g/mol * 0.41 mol = 16.049 g. So, the mass of 0.41 mol of potassium is approximately 16.049 grams.
What is the mass in g of 0.375 mol of the element k?
To find the mass of 0.375 moles of potassium (K), you need to multiply the moles by the molar mass of potassium (39.10 g/mol). 0.375 mol * 39.10 g/mol = 14.6625 g 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 relative formula mass of potassium carbonate?
The relative formula mass of potassium carbonate (K2CO3) is 138.21 g/mol. This value is calculated by adding the atomic masses of each element in the compound: potassium (K) has a molar mass of 39.10 g/mol, carbon (C) has a molar mass of 12.01 g/mol, and oxygen (O) has a molar mass of 16.00 g/mol.
What is the mass of 7.111 mol of potassium sulfide?
To calculate the mass of 7.111 mol of potassium sulfide (K2S), you need to multiply the number of moles (7.111 mol) by the molar mass of K2S (which is 110.26 g/mol). Therefore, the mass of 7.111 mol of potassium sulfide is 783.83 grams.
What is the mass of 1.48 mol of potassium sulfide?
To find the mass of 1.48 mol of potassium sulfide (K2S), you need to multiply the molar mass of K2S by the number of moles given. The molar mass of K2S is approximately 110.3 g/mol. Therefore, the mass of 1.48 mol of potassium sulfide would be 1.48 mol * 110.3 g/mol = 163.2 grams.

How many grams of potassium are in 27.8 g of K2CrO7?
To find the grams of potassium in K2CrO7, first determine its molar mass. Potassium (K) has a molar mass of 39.10 g/mol, and K2CrO7 has two potassium atoms, so (39.10 g/mol) * 2 = 78.20 g/mol. Then, divide the mass of K2CrO7 by its molar mass to get the grams of potassium: (27.8 g) / (294.19 g/mol) ≈ 9.45 g of potassium.
