Question

In six moles of Ethane 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

Explanation:

no of molecules = n ×Na

= 6× 6.022×10^23

= 18.013 × 10^23

Answer 2

Answer:

Explanation:

(i) 1 mole of C2H6 contains 2 moles of carbon atoms.

Number of moles of carbon atoms in 3 moles of C2H6

= 2 × 3 = 6

(ii) 1 mole of C2H6 contains 6 moles of hydrogen atoms.

Number of moles of carbon atoms in 3 moles of C2H6

= 3 × 6 = 18

(iii) 1 mole of C2H6 contains 6.023 × 1023 molecules of ethane.

Number of molecules in 3 moles of C2H6

= 3 × 6.023 × 1023 = 18.069 × 1023
