if we approximate the atmosphere to be 79% nitrogen (n2) and 21% oxygen (o2) by volume, calculate the density of air (kg/m3) at stp conditions (0oc, 1 atm). hint: 1 mole of gas occupies 22.414 l at stp.

How much heat is released upon converting one mole of steam (18.0 g) from 100.0 ∘c to water at 25.0 ∘c? show work and constants, trying to figure out how it works. only given the heat capacity for steam and water so try to only use that
