When 0.01 mol of an organic compound containing 60% carbon was burnt completely, 4.4 g of CO$_2$ was produced. The molar mass of compound is _____________ g mol$^{-1}$ (Nearest integer).
Answer (integer)
200
Solution
<p>Number of moles of $C{O_2} = {{4.4} \over {44}} = 0.1$</p>
<p>$\therefore$ Number of moles of C in 1 mole of compound = 10</p>
<p>$\therefore$ $120 = {{60} \over {100}} \times (x)$ [where x is molar mass of OC]</p>
<p>Molar mass = 200 g mol$^{-1}$</p>
