Answer
(a) 1 mole C2H6 contains two moles of C- atoms.
∴ No. of moles of C- atoms in 3 moles of C2H6.
= 2 * 3
= 6
(b) 1 mole C2H6 contains six moles of H- atoms.
∴ No. of moles of C- atoms in 3 moles of C2H6.
= 3 * 6
= 18
(c) 1 mole C2H6 contains six moles of H- atoms.
∴ No. of molecules in 3 moles of C2H6.
= 3 * 6.023 * 1023
= 18.069 * 1023

Answer:
- No of moles of c atom in 3 moles of ehane is 2c per mole so for three they will be 6
- No of moles of H atom per mole is 6 so for three mole of ethene they will be 18
- No of molecules is = No of moles × avagadro No
- avagadro No = 6.023 × [10] 23
so answer is ~ 18.069 ×[10] 23 ✓✓✓✓✓
hope it will be helpful to you
