Question

The no of molecules and number of atoms present in 0.001 mol of phosphorus molecules respectively are

Answer 1

Answer:

6.022×10²⁰ and 2.4088 ×10²¹

Answer 2

Answer:

Molecules of phosphorous in 0.001 moles = $6.022\times 10^{20}$

Atoms of phosphorous in 0.001 moles=24.088\times 10^{20}[/tex]

Explanation:

Phosphorous molecule = $P_4$

1 mole of Phosphorous molecule contains 6.022×10²³ molecules

0.001 mole of Phosphorous molecule contains 6.022×10²³*0.001 molecules

Molecules of phosphorous in 0.001 moles = $6.022\times 10^{20}$

1 molecule contains 4 atoms.

So,

Atoms of phosphorous in 0.001 moles = $4\times 6.022\times 10^{20}=24.088\times 10^{20}$
