Question

1 - Calculate the number of electrons present in one mole of ethane?​

Answer 1

Answer:

18 Na electron

Explanation:

1 molecule = 18 electrons

1 mole molecule = 18 Na electrons

Answer 2

Answer:

108.414×10^23 electrons

Explanation:

1 mole of Ethane (C2H6) = 2 moles of C + 6 moles H atoms.

So , as we know that one mole of carbon atom(C) contains 6 electrons.

Hence 2 moles of carbon atom will contain 2×6 electrons= 12.

And, one mole Hydrogen atoms contain 1 electron.

So,1 mole of ethane( C2H6) will contain= 12+6= 18 electrons.

Now , we know that 1mole = 6.023 × 10^23.

Hence 1 mole of ethane = 18× 6.023× 10^23.

=108.414×10^23 electrons.

Ethane belongs to the alkane group which has a single bond between two carbon atoms and each are paired by hydrogen atoms.
