Question

How many `C` atoms are there in 0.502 mole of `C`?

Answer 1

`3.0231147xx10^24`

Explanation:

The number of atoms in a single mole of any substance is defined by Avogadro's Number, a constant which is equal to `6.0221409xx 10^23`, so there are approximately `6.0221409xx 10^23` atoms in a single mole of a substance.

To find the number of atoms in a given amount of substance, simply multiply the amount in moles of the substance by Avogadro's Number:

Number of `C` atoms `= 5.02 xx 6.0221409xx 10^23 = 3.0231147xx10^24`
