Respuesta :
The answer is B
The only info you need is the number of moles
0.30 mol × 6.022×10²³/mol = 1.806×10²³
There are 1.806 x 10^23 atoms in 0.30 moles of sulfur dioxide gas.
Mole calculation
To calculate the number of atoms present in a mole value, use Avogadro's constant, so that:
[tex]C = 6.02 \times 10^{23^}[/tex]
[tex]n = mol \times C[/tex]
So, applying the values given in the question in the expression above:
[tex]n = 3 \times 6.02 \times 10^{23^}[/tex]
[tex]n = 1.806 \times 10^{23}[/tex]
So, there are 1.806 x 10^23 atoms in 0.30 moles of sulfur dioxide gas.
