Question

How many moles are in 4.64 x 1025 atoms of H2CO3?

Answer 1

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:


`4,64*10^(25) molecules H_2CO_3* (1 mol H_2CO_3)/(6,02*10^(23) molecules)=77,08 moles`

So, there are 77,08 moles of H₂CO₃

Have a nice day!
