In order to calculate the mass of nitrogen, we must first calculate the mass percentage of nitrogen in potassium nitrate. This is: % nitrogen = mass of nitrogen / mass of potassium nitrate % nitrogen = 14 / 101.1 x 100
The mass of nitrogen = % nitrogen x sample mass = (14 / 101.1) x 101.1 = 14 grams
The molar weight of nitrogen is 14. Each mole of urea contains two moles of nitrogen. Therefore, for there to be 14 grams of nitrogen, there must be 0.5 moles of urea. Mass of urea = moles urea x molecular weight urea Mass of urea = 0.5 x 66.06 Mass of urea = 33.03 grams
Since a radical is formed as part of the product it means it's a propagation step and not a termination step, at termination no free radical exist as product
