As the ionization energies of the elements decreases down the group carbon has got the highest ionization energy in the group being at the top of the group.

Carbon is on the top of the group 4 among the given elements. Hence, Carbon has the highest ionization energy.

The gram formula mass of a compound is nothing but the molar mass.

The molar mass of K2CO3 (Potassium Carbonate) is given by

Atomic weights of individual elements are

K (Potassium) = 39 g

C (Carbon) = 12 g

O (Oxygen) = 16 g

Hence, that of K2CO3 = 39(2) + 12 + 16(3)

= 78 + 12 + 48

= 138.

The main purpose in measuring the effectiveness of any advertising campaigns is to evaluate its effect on the sales and also brand recall factor. The mathematical equation for measuring the effectiveness of an advertising campaign is:
