Question

How many aroms of c,h,o are present in 10 moleculesod c2h4?

Answer 1

Answer:

1.25 x 10^25 atoms of C and 2.4 x 10^25 atoms of H

Explanation:

1 molecule of c2h4 contains 6.022 x 10^23 x 2 atoms of carbon                    =1.2 x 10^24 atoms

10 molecules = 10 x 1.2 x 10^24 atoms of carbon = 1.2 x 10^25 atoms

Similarly 1 molecule of c2h4 contains 6.022 x 10^23 x 4 atoms of Hydrogen

=2.4 x 10^24 atoms

10 molecules = 10 x 2.4 x 10^24 atoms of Hydrogen = 2.4 x 10^25 atoms

And Finally , c2h4 do not contain any Oxygen atoms in it.

Hope this helps you!!!
