Question

what is the mass of 4 miles of carbon atoms​

Answer 1

Explanation:

1 mole of any element contains 6.022×10^23 atoms .

So, 1 mole of carbon contains 6.022×10^23 carbon atoms . So, 4 mole of carbon element contains 4×(6.022×10^23) carbon atoms. That is equal to 24.088 ×10^23 carbon atoms.

Mass of 6.022×10^23 carbon atoms is 12 gram

So, mass of 4mole of carbon atoms(mass of 24.088×10^23carbon atoms)=12×4=48grams

Or 48×6.024×10^23 amu=289.152×10^23 amu
