4.which is a product of the process shown above? a. carbon dioxide
b. sugar
c. sunlight
d. water

5.where does the energy that drives this process come from?
a. oxygen
b. sugar
c. sunlight
d. water

4. b 5.C

Explanation:

Photosynthesis makes sugar for plants and sunlight is the energy used to convert CO2 and water into glucose

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.
