4b. Using the principle of the law of definite proportion, show
that 50.5g CO2 and 88.6g CO2 contain the same element in the
same mass ratio.

explanation:

each principal energy level above the first contains one s orbital and three p orbitals. a set of three p orbitals, called the p sublevel, can hold a maximum of six electrons. therefore, the second level can contain a maximum of eight electrons - that is, two in the s orbital and 6 in the three p orbitals.
