How many moles are in 75.0 grams of nitrogen gas, N2?

Given:                                                                                                                      

Mass of Nitrogen (N₂) gas = 75 grams

Finding the number of moles of N₂:                                                                    

We know that the molar mass of N₂ is 28 grams/mole

Number of moles = Given mass / Molar mass

Number of moles = 75 / 28

Number of moles = 2.68 moles

Hence, there are 2.68 moles in 75 grams of Nitrogen Gas
