In three moles of ethane (C2H6), calculate the following:

(i) Number of moles of carbon atoms.

(ii) Number of moles of hydrogen atom

(iii) Number of molecules of ethane

##### Solution :-

(a) 1 mole$$C_{2}H_{6}$$ contains two moles of C- atoms.

$$∴$$ No. of moles of C- atoms in 3 moles of $$C_{2}H_{6}$$

= 2 * 3

= 6

(b) 1 mole $$C_{2}H_{6}$$contains six moles of H- atoms.

∴ No. of moles of C- atoms in 3 moles of $$C_{2}H_{6}$$

= 3 * 6

= 18

(c) 1 mole $$C_{2}H_{6}$$ contains 1 mole of ethane- atoms.

∴ No. of molecules in 3 moles of $$C_{2}H_{6}$$.

= 3 * 6.023 * $$10^{23}$$

= 18.069 * $$10^{23}$$
