<span>Photosynthesis is the process in plants to make their food. This involves the use carbon dioxide to react with water and make sugar or glucose as the main product and oxygen as a by-product. Since we are not given the mass of CO2 in this problem, we assume that we have 1 g of CO2 available. We calculate as follows:</span>

<span>
</span>

<span>1 g CO2 ( 1 mol CO2 / 44.01 g CO2 ) ( 12 mol H2O / 6 mol CO2 ) ( 18.02 g / 1 mol ) = 0.82 g of H2O is needed</span>

<span>
</span>

However, if the amount given of CO2 is not one gram, then you can simply change the starting value in the calculation and solve for the mass of water needed.

Chloroplast is This organelle of a cell, is where chlorophyll is found. The organelle most involved in photosynthesis.








Hope that helps!!! :)



Chlorophyll is a green pigment present in all plants, that absorbs light to provide energy for photosynthesis.
