A mole (more properly called a "gram Atomic Mass") of K contains Avogadro's Number of atoms. Therefore, 0.0384 moles contains 0.0384 X Avogadro's Number or about 2.31 X 1022 atoms, to the justified number of significant digits.

What is the concentration of K in 0.15M of K2S?
If you have 2 moles of K+ for every mole of K2S and Molarity (M) is Moles per Liter. Then you know that you have .30 M of K2S. The way that you do that is setting up a series of conversion factors like so:(.15moles k2s/liter) x (2 moles of K/ 1 mole of K2S) = .30 moles k/ liter.The moles of K2S cancel out and you are left with moles of K per liter.

How many atoms of potassium need to react with nitrogen in order to produce 2.0 moles of potassium nitride?
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.
How many atoms are in 3.50 moles of calcium?
There are 6.022 × 1023 atoms of potassium in every mole of potassium. Since one mole of KOH contains one mole of K, the answer is 6.022×1023 atoms of K. Therefore, 3.5 moles * 6.022E23 atoms/1 mole= 2.107E24
How many moles of atoms are contained in 6.81 x 1024K atoms?
There are 1 mole of atoms in 6.022 x 10^23 atoms (Avogadro's number). Therefore, to find the number of moles in 6.81 x 10^24 atoms, you would divide the given number of atoms by Avogadro's number: 6.81 x 10^24 atoms / 6.022 x 10^23 atoms/mole = 11.33 moles.
How many atoms are present in 3.8 mol of k?
To find the number of atoms in 3.8 moles of potassium (K), you can use Avogadro's number, which is approximately (6.022 \times 10^{23}) atoms per mole. Multiply the number of moles by Avogadro's number: [ 3.8 , \text{mol} \times 6.022 \times 10^{23} , \text{atoms/mol} \approx 2.28 \times 10^{24} , \text{atoms}. ] Therefore, there are approximately (2.28 \times 10^{24}) atoms in 3.8 moles of potassium.

How many atoms of K in 2.77g of KCl?
To find the number of K atoms in KCl, we first calculate the molar mass of KCl: 39.10 (K) + 35.45 (Cl) = 74.55 g/mol. Next, we determine the number of moles of KCl in 2.77g: 2.77g / 74.55 g/mol = 0.0371 mol. Since there is 1 K atom in 1 KCl molecule, the number of K atoms in 2.77g of KCl is the same as the number of moles of KCl, which is 0.0371 mol.
