Question

0.66g of a compound gave 112ml of nitrogen measured at stp in dumas method the percentage of nitrogen in compound is

Answer 1

Answer:

Dumas method is a procedure that is followed in analytical chemistry to determine an unknown chemical compound's molecular weight. This procedure was designed by  Jean-Baptiste Dumas back in 1826.

This method is profoundly more suitable for finding volatile organic compounds' molecular weight.

Percentage of Nitrogen:                                    

=$\frac{Volume of Nitrogen at STP}{8 * Mass of the Compound}$

=   $\frac{112}{8* 0.66}$

= 9.24 %

Hence the Nitrogen percentage in the compound is 9.24%
