In Duma's method,the gas which is collected in Nitromer is 0.35 g of an organic compound gave 55 mL of nitrogen collected at 300 K temperature and 715 mm pressure .The precentage composition of nitrogen in the compound would be :
(Aqueous tension at 300 K= 15 mm)

Options

A. 17.45
B. 14.45
C. 15.45
D. 16.45

Answer

D

Explanation

`(P_(1)V_(1))/(T_(1))=(P_(2)V_(2))/(T_(2))`
`V_2=(P_(2)V_(2)T_(2))/(T_(1)P_(2))=((715-15)xx55xx273)/(300 xx 760)`
`=(700xx55xx273)/(300 xx 760)=46 mL `
`" Mass of " N_(2)=(46)/(22400)xx 28 = 0.058 g`
