Calculate the weight percent of nitrogen in melamine and cyanuric acid and compare this value to the average percent of nitrogen in protein (14%).

Interpretation Introduction

Interpretation:

It should be calculate and compare the weight percentage of nitrogen in melamine and cyanuric acid with the average percent of nitrogen in protein.

Concept Introduction:

Percentage of Weight: The grams of solute in 100 grams of solution, the fallowing formula is,

Percentageweight=Weightofsolute(g)Weightofsolution(g)×100

A hydrogen bonding is partially an electrostatic attraction between H atom which is bonded to more electronegative atom such as N, O, orF and another adjacent atom bearing a lone pair of electron.

Explanation of Solution

The chemical formula for melamine is C3H6N6 so the molecular weight of melamine is

C3H6N6Massofcarbonatoms=3×12=36Massofhydrogenatoms=1.01×6=6.01Massofnitrogenatom=14.01×6=84Totalmassvalueofgivencompound=126.13

Next we calculate the mass melamine N%

In melamine=Molecularweightofnitrogen=84=84126×100=66
