How many moles of nitrogen are contained in a 35.0g sample?

Answer 1

35.0 moles nitrogen (1 mole N/14.01 grams)

= 2.50 moles nitrogen

----------------------------

Answer 2

To find the number of moles of nitrogen in a 35.0g sample, you need to divide the mass of the sample by the molar mass of nitrogen. The molar mass of nitrogen is approximately 14.01 g/mol. Therefore, 35.0g / 14.01 g/mol = approximately 2.5 moles of nitrogen.
