When the ground gets warm, it emits an invisible type of light called infrared light. this light can travel into the atmosphere and heat the air that it encounters. what type of heat transfer is described above? a. convection b. conduction c. radiation d. precipitation

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

10

23

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

f

6

will have a gram-molecular weight of 352g.

b
