Question

How many atoms are in 2.50 moles of n?

Answer 1

There are
`15.055 × 1023`atoms in
`2.50 moles` of a substance, calculated by multiplying the number of moles by Avogadro's number which is

`6.022 × 1023 atoms per mole`.

Step-by-step explanation:

To calculate how many atoms are in
`2.50 moles`of a substance, we use Avogadro's number, which is
`6.022 × 1023 atoms per mole`. The number of atoms (N) can be found by multiplying the number of moles (n) by Avogadro's number (NA)

Here's the calculation:

1. Identify the number of moles:
   `n = 2.50 moles`.
2. Multiply the moles by Avogadro's number:
3. 
   `N = n × NA = 2.50 moles × 6.022 × 1023 atoms/mole.`
4. Calculate the result:
   `N = 15.055 × 1023 atoms`.

Therefore, there are
`15.055 × 1023 atoms` in
`2.50 moles` of the substance.
