Answer:2.07 x 10 24 atoms of P
Explanation:To find the number of atoms in the given moles of the element follow the following steps:
Step 1 : Use the avogadro number to convert the moles to atoms.We know that 1 mole of any atom ,compound,formula unit has 6.02 x 1023 atom,compound or formula unit .In the problem given here there are 3.44 moles of P atom .
1 mole of P atom = 6.02 x 1023 atoms of P
Step 2 : How many atoms will be in 3.44 moles of phosphorus.Use the formula
Given x conversion factor
(given is the condition given in the problem and A conversion factor is a ratio (or fraction) which represents the relationship between two different units) .
3.44 moles of P x 6 .02 x 1023 atoms of P / 1 mole of P atoms = 2.07 x 10 24 atoms of P
