Question
A compound contains 36% carbon by mass. If each molecule contains two carbon atoms, the number of moles of compound in its 10 g is
Options
A.66.67
B.0.15
C.0.30
D.1.5
Solution
$36 = \frac{2 \times 12}{M} \times 100 \Rightarrow M = \frac{200}{3}$
Hence, moles of compound = $\frac{10}{\left( \frac{200}{3} \right)} = 0.15$
