<span>The equation that represents the process of
photosynthesis
is: 6CO2+12H2O+light->C6H12O6+6O2+6H2O. 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.</span>
The mole number of helium is 8/4=2 mol. Under same condition, the volume of gas is related to the mole number of the gas. So the mole number of chlorine is also 2 mol which is 142 g.
