Gennadij [26K]3 years ago
8 0

Answer:

d) 8.01 E23 atoms

Explanation:

  • mol ≡ 6.022 E23 atoms

∴ mass C = 16 g

∴ molar mass C = 12.0107 g/mol

⇒ mol C = (16 g)*(mol/12.0107 g) = 1.332 mol

⇒ atoms C = (1.332 mol)*(6.022 E23 atoms/mol)

⇒ atoms C = 8.02 E23 atoms

4. Did the complete process of photosynthesis take place in the way you modeled it in this activity? Explain your answer
weqwewe [10]
Hello!

This question requires a model -- you'll have to do that yourself. However, I can explain the steps for the process:

• Chlorophyll absorbs the sun's energy.

• The energy is used to split water molecules into hydrogen and oxygen.

• The oxygen is released from the leaves into the atmosphere.

• The hydrogen and carbon dioxide glucose (food) for plants.
