The Henry’s Law constant for nitrous oxide in water is 2.4 x 10-2 molal/bar. Determine the mass of N2O that will dissolve in 250 mL of water, under an N2O pressure of 3.3 bar. The density of water at 25 ºC is 1.0 g/ml.

D. is the answer hope that you

Ch4 and ph3 are both covalent since they are composed both of non-metals.    ch4 is non- polar because of  london forces and has a geometry of tetrahedral  ph3 , on the other hand, is umbrella shaped polar and has dipole-dipole intermolecular force (imf) . since ph3 is polar, it has a stronger imf   

Idon't hope someone you
