Question

calculate the number of atoms in 0.5 mole atoms of SO2

Answer 1

Answer:

The number of atoms in 0.5 mole atoms of  SO₂ gas will be equal to 9.0345 ×10²³ atoms.

Explanation:

We have given,

The number of moles of SO₂ = 0.5 moles

The number of molecules in 1 mole of SO₂ gas = 6.023×10²³

Number of molecules in 0.5 moles of SO₂ gas = 6.023×10²³×0.5

                                                                          =  3.0115 ×10²³  molecules

The number of atoms in 1 molecule = 3 atoms

Number of atoms in 3.0115 ×10²³  molecules =  3.0115 ×10²³× 3

                                                                         =  9.0345 ×10²³ atoms.

Therefore, the total number of atoms present in 0.5 moles of SO₂ gas is equal to 9.0345 ×10²³ atoms.
