1.	0.92 g of an organic compound was analysed by combustion method. The mass of the U-tube increased by 1.08 g. what is the percentage of hydrogen in the compound?
Answer» 0.1304 0.5217 0.6521 0.113 Solution :INCREASE in mass of U-tube =1.08g mass of WATER formed=1.08g 18g `H_(2)O-=2` g H `1.08" g "H_(2)O=(2)/(18)xx1.08` % of hydrogen=`(2)/(18)xx(1.08)/(0.92)xx100=13.04%`
