1.4 moles of phosphorus trichloride are present in a sample. How many ...
To determine the number of atoms present in a sample of phosphorus trichloride, we need to use Avogadro's number, which states that 1 mole of any substance contains 6.022 × 10^23 entities (atoms, molecules, or ions).
Given:
Moles of phosphorus trichloride = 1.4 moles
To find the number of atoms, we need to multiply the number of moles by Avogadro's number:
Number of atoms = Moles of substance × Avogadro's number
Let's calculate the number of atoms in the sample:
Number of atoms = 1.4 moles × 6.022 × 10^23 atoms/mole
Solving this equation, we get:
Number of atoms = 8.4308 × 10^23 atoms
Therefore, the correct answer is option D: 3.372 × 10^24 atoms.
