Question

Convert 1.83 × 1024 atoms of carbon to moles of carbon.

Answer 1

1 mole C ---------------- 6.02x10²³ atoms
?? moles C ------------- 1.83x10²⁴ atoms

1 x ( 1.83x10²⁴ ) / 6.02x10²³ =

1.83x10²⁴ / 6.02x10²³ => 3.03 moles of C

hope this helps!

Answer 2

Answer:

3.0 moles of carbon

Explanation:

To solve this problem is useful to know the Avogadro´s number, it relates the number of atoms in a mol of an element. In this case the element is the carbon, but Avogadro´s number is useful for all elements.

The Avogadro´s number is equal to $[tex]6.022*10^{23}\frac{atoms}{mol}$[/tex].

And to convert from atoms of carbon to moles of carbon we need to use the following relationship:

$1.83*10^{24}atomsofcarbon*\frac{1molofcarbon}{6.022*10^{23}atomsofcarbon}=3.0$ moles of carbon
