In the Kjeldahl's method for estimation of nitrogen in a soil sample, ammonia evolved from 0.75 g of sample neutralised 10 ml of 1 M `H_(2) SO_(4)`. The percentage of nitrogen in the soil is

A

37.33

B

45.33

C

35.33

D

43.33

Text Solution

Verified by Experts

The correct Answer is:
A
Percentage of nitrogen `= (1.4xxN xx V)/(w) = (1.4xx10xx2)/(0.75) = 37.33%`
