I believe the answer is Chlorophyll. During photosynthesis light energy from the sun is trapped by chlorophyll, it is then used to break down water molecules to hydrogen ions and oxygen gas. This represent the first stage of photosynthesis called light dependent stage. The hydrogen ions formed in this stage then joins the light independent stage (dark stage) and oxygen is released to the atmosphere or released to the atmosphere.
I believe the correct answer is A.

- How many moles of this element are there?
1000000 atoms ( 1 mol / 6.022x10^23 atoms ) = 1.66 x 10^-18 mol of the element
- What is the molar mass of this element?
Molar mass = 1.99 x 10 ^-17 grams / 1.66 x 10^-18 mol = 11.98 g/mol
- What is the identity of this element?
The identity most likely is closest to carbon which has a molar mass of 12.01 g/mol.
