How many molecules of ethane ( C2H6) are present in 0.197g of C2H6?
Brut [27]

Answer:

3.945 x 10²¹ molecules

Explanation:

  • Firstly, we need to calculate the no. of moles using the relation:
  • n = mass/molar mass = (0.197 g)/(30.07 g/mol) = 6.55 x 10⁻³ mol.
  • It is known that every 1.0 mol of a molecule contains Avogadro's number of molecules (NA = 6.022 x 10²³).
  • <em>∴ 0.197 g of C₂H₆ will contain</em> = (6.55 x 10⁻³ mol)(6.022 x 10²³) = <em>3.945 x 10²¹ molecules.</em>
