Question

How many atoms are in 0.580 moles of CO2?

Answer 1

`1.05x10^(24)atoms`

Step-by-step explanation:

Hello!

In this case, according to the definition of the Avogadro's number, it is possible to realize that one molecule of CO2 contains 3 moles of atoms, one of carbon and two of oxygen, thus, we have:

`0.580molCO_2*(3mol\ atoms)/(1molCO_2) =1.74mol\ atoms`

Then, we use the Avogadro's number to obtain:

`1.74mol\ atoms*(6.022x10^(23)atoms)/(1mol\ atoms) \\\\1.05x10^(24)atoms`

Best regards!
