Question

1.10
In three moles of ethane (C2H6), calculate the following
(1) Number of moles of carbon
atoms,
(ii) Number of moles of hydrogen atoms.
(111) Number of molecules of ethane.​

Answer 1

Answer:

Carbon atoms - 2

Hydrogen atoms - 6

Number of moles of carbon atoms = 3 × 2 = 6mol

Number of moles of hydrogen atoms = 3 × 6 = 18mol

Number of molecules of ethane = 3 × 6.023 × 10^23 = 1.8069 × 10^24.
