To calculate the mass of 2.60 mol of potassium chloride (KCl), first determine its molar mass. The molar mass of K (potassium) is approximately 39.10 g/mol, and Cl (chlorine) is about 35.45 g/mol, giving KCl a molar mass of about 74.55 g/mol. Multiplying the number of moles by the molar mass, we have 2.60 mol × 74.55 g/mol = 193.83 g. Therefore, the mass of 2.60 mol of potassium chloride is approximately 193.83 grams.

To calculate the mass of 2.60 moles 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 potassium and 35.45 g/mol for chlorine). Therefore, the mass can be calculated using the formula: mass = moles × molar mass. Thus, the mass of 2.60 mol of KCl is 2.60 mol × 74.55 g/mol = 193.83 grams.
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.
0,806 mol of the element potassium (K) is equal to 31,51 g.
The molar mass of the element potassium is 39 g/mol.
40*0.561=22.44g
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.
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.
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.
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.
To calculate the mass of 2.60 mol of potassium chloride (KCl), first determine its molar mass. The molar mass of K (potassium) is approximately 39.10 g/mol, and Cl (chlorine) is about 35.45 g/mol, giving KCl a molar mass of about 74.55 g/mol. Multiplying the number of moles by the molar mass, we have 2.60 mol × 74.55 g/mol = 193.83 g. Therefore, the mass of 2.60 mol of potassium chloride is approximately 193.83 grams.
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.
