Walker Esparza · Answer 1

To calculate the number of moles of a substance, divide the amount of substance with the molar mass. The molar mass of nitrogen is approximately 14 grams per mole. Divide the given 21.2 g of N with the molar mass. The division will give an answer of 1.514 moles. Thus, there are approximately 1.514 moles of nitrogen in the sample.
