Question

In three moles of ethane (C2H6), Calculate the following.

(i)Number of moles of carbon atoms
(ii) Number of moles of Hydrogen atoms
(iii) Number of molecules of ethane.​

Answer 1

Answer:

1.6

2.18

3.18.069×10²³

Explanation:

1.1 molecule of ethane contains 2 carbon atoms

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

2.1 molecule of ethane contains 6 hydrogen atoms

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

3.1 mole of ethane contains 6.023×10²³ molecules of ethane

so 3 mole of ethane contains 3×6.023×10²³ =18.069 ×10²³ molecules of ethane
