Calculate the density, in g/l, of n2 gas at 35°c and 0.98 atm pressure.?

Assuming that N2 is ideal, then we could use the ideal gas equation:

PV = nRT. Rearranging to solve for density,

density = PM/RT, where M is the molar mass

substituting:

density = [(0.98 atm)(28 g/mol)]/[(0.08206)(35+273 K)] = 1.08 g/L

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .
