Step 1

The number of moles in the given mass of the gaseous molecule is calculated as shown in equation (1). In equation (1), ng, mg, and Mg are the moles, given mass, and molar mass of the given gas. In order to calculate the number of moles of nitrogen (nN2), the values of the mass of nitrogen and molar mass of nitrogen is substituted in equation (1). The number of mole of nitrogen is 0.17 mole.
