    given mass / molar mass * (6.022*10^23) will give u the no of molecules

    \[57.3gC2H6 \times \frac{6.02 \times 10^{23} moleculesC2H6}{30gC2H6}\]

    Chemical formula of ethane = C2H6 no. of mole of ethane = 57.3 / (12.0x2+1.0x6) = 57.3/30 = 1.91 mole no. of molecules required = no. of mole x Avogadro's Constant = 1.91 x (6.02x10^23) = ?
