25 g of an unknown hydrocarbon upon burning produces 88 g of $CO_{2}$ and 9 g of $H_{2} O$ . This unknown hydrocarbon contains:

Answer:

Solution:

$C_{x} H_{y} + O_{2} \to XCO_{2} + \frac{y}{2} H_{2} O$

Wt of carbon $= \frac{88}{44} \times 12 = 24 g$

Wt of hydrogen $= \frac{9}{18} \times 2 = 1 g$
