During nitrogen estimation present in an organic compound by Kjeldahl’s method, the ammonia evolved from 0.5g of the compound in Kjeldahl’s estimation of nitrogen neutralised 10 mL of 1M H₂SO₄. Find the percentage of nitrogen in the compound.

Solution

Mass of the organic compound taken = 0.5 g
Volume of $1 MH subscript 2 SO subscript 4$ required for neutralising ammonia = 10 mL
$therefore space space 10 space mL space of space 1 straight M space straight H subscript 2 SO subscript 4 space equals space 20 space mL space of space 1 straight M space NH subscript 3$
$Now space 1000 space mL space of space 1 straight M space ammonia space contains space 14 space straight g space nitrogen space space space space space space space therefore space space space 20 space mL space of space 1 straight M space ammonia space would space contain space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space equals 14 over 100 cross times 20 space straight g space nitrogen therefore space space space Percentage space of space nitrogen space equals space fraction numerator 14 space cross times space 20 over denominator 1000 end fraction cross times fraction numerator 100 over denominator 0.5 end fraction space equals space 56.0 percent sign$
