how many atoms are in 0.30 moles of sulfur dioxide gas at stp?

A. 6.0 x 10 ^23
B. 1.806 x 10 ^23
C. 2.01 x 10 ^24
D. 1,806

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.
