Thank you for the opportunity to help you with your question!

 density of nitrogen 1.17X10^-3g/cm^3

mass = density * volume

mass = 1.17X10^-3g/cm^3 *2500cm3 = 1.77 *25 *10^-3*100 = 29.25 *10^-1 g

= 2.925 g

Please let me know if you need any clarification. I'm always happy to answer your questions.
