A tank contains 0.5 m3 of nitrogen (N2) at -71 C and 1356 kPa. Determine the mass of nitrogen, in kg, using the ideal gas model.

☆ionisation energy increases across a period from na -> ar☆ionisation energy decreases down a group from li -> fr☆ionic radius decreases across a period from na -> cl☆ionic radius increases down a groupfrom f -> ii hope it clarifies your doubts

What are the options? physical property can be color, smell, opacity, viscosity, density, infra red spectrum, melting and boiling points, attraction and repulson to magnets, etc.

I’m really not sure what’s the answer. sorry
