There are 3.88 * 10²⁴ atoms of potassium in 2.15 moles of potassium phosphate.
The formula of potassium phosphate is K₃PO₄ and the formula of potassium is K.
1 mole of potassium phosphate contains 3 moles of Potassium atoms
2.15 moles of potassium phosphate contains 2.15 * 3 moles of Potassium atoms
2.15 moles of potassium phosphate contains 6.45 moles of Potassium atoms
Number of atoms in 6.45 moles of potassium atom = 6.45 * 6.02 * 10²³
Number of atoms in 6.45 moles of potassium atom = 3.88 * 10²⁴ atoms
Therefore, there are 3.88 * 10²⁴ atoms of potassium in 2.15 moles of potassium phosphate.
