Final answer:

The mass of 6 atoms of copper is 381.24 g.

Step-by-step explanation:

The atomic mass of copper is 63.54 g/mol and the number of copper atoms is given as 4.739 x 1023 atoms. To find the mass of 6 atoms of copper, we can use the formula:

Mass = Atomic mass x Number of atoms

So, the mass of 6 atoms of copper would be:

Mass = 63.54 g/mol x 6 atoms = 381.24 g

Answer:

6.33×10¯²² g

Step-by-step explanation:

From the question given above, the following data were obtained:

Number of atoms = 6 atoms

Mass of copper (Cu) =?

From Avogadro's hypothesis, we understood that:

6.02×10²³ atoms = 1 mole of Cu

But 1 mole of Cu = 63.5 g

Thus,

6.02×10²³ atoms = 63.5 g of Cu

Finally, we shall determine the mass of 6 atoms of copper. This can be obtained as illustrated below:

6.02×10²³ atoms = 63.5 g of Cu

Therefore,

6 atoms = (6 × 63.5) / 6.02×10²³

6 atoms = 6.33×10¯²² g of Cu

Therefore, the mass of 6 atoms of copper is 6.33×10¯²² g.
