Answer: 7.608 x 10∧23
Explanation:
Using Avogadro's Number;
1 mole of Phosphorus (P4) molecule contains 6.02 x 10∧23 molecules.
∴ 0.316 mole of Phosphorus (P4) will contain; 0.316 x 6.02 x 10∧23 =
1.902 x 10∧23 molecules.
1 molecule of Phosphorus (P4) is made up of 4 atoms.
∴ 1.902 x 10∧23 molecules Phosphorus (P4) will contain :
1.902 x 10∧23 x 4 = 7.608 x 10∧23 atoms
0.316 mole of phosphorus contains 7.608 x 10∧23 atoms.
