Sagot :

There are 3.88 * 10²⁴ atoms of potassium in 2.15 moles of potassium phosphate.

Definition of molar mass and mole

  • The molar mass of a substance is the mass of one mole of the substance
  • A mole of substance is the amount of that substance that contains the Avogadro number of particles which is equal to 6.02 * 10²³ particles.

Formula 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.
