Question

In three moles of ethane (C,H.), calculate the following:
(i) Number of moles of carbon atoms.
(in Number of moles of hydrogen atoms.
(iii) Number of molecules of ethane. ​

Answer 1

Explanation:

so 3 moles of ethane contains 6 mole of carbon atoms. so 3 moles of ethane contains 18 mole of hydrogen atoms

Answer 2

Answer:

mark me as brainlist

Explanation:

1 mole of ethane (C2

H6  ) has 2 moles of carbon and 6 moles of hydrogen.

We are given 3 moles of ethane.

(i) Number of moles of carbon atoms =3×2=6 mol

(ii) Number of moles of hydrogen atoms =3×6=18 mol

(iii) Number of molecules of ethane =3 × 6.023 × 10  ^23  = 1.8069 × 10  ^24
