Two different compounds are formed by the elements nitrogen and oxygen. the first compound, compound p1, contains 64.17% by mass nitrogen and 35.73% by mass oxygen. the second compound, compound p2, contains 47.23% by mass nitrogen and 52.79% by mass oxygen. what is the ratio of nitrogen to a fixed mass of oxygen for the two compounds?

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."
