How many moles are in 4.64 x 1025 atoms of h2co3?

Hello there!

To solve this question, we are going to use the Avogadro's Number. The Avogadro's Number (6,02*10²³ molecules/mol) tells us how many molecules are in a mole of any given substance.

For 4,64 * 10²⁵ atoms of H₂CO₃, we can use the following conversion factor:



So, there are 77,08 moles of H₂CO₃

Have a nice day!
