Question

25 g of an unknown hydrocarbon upon burnig produces 88 g of C O 2 and 9 g of H 2 O . This unknown hydrocarbon contains:, 24 g of carbon and 1 g of hydrogen, 18 g of carbon annd 7 g of hydrogen, 22 g of carbon and 3 g of hydrogen, 20 g carbon and 5 g of hydrogen

MARKS App · Accepted Answer

2 m o l e of C O 2 contains 2 m o l e of carbon, Hence weight of carbon = 2 × 12 = 24 g . mass of Hydrogen = 25 - 24 = 1 g r a m
