Atomic mass of an element is not a whole number because It contains isotopes. For example, chlorine has two isotopes 1735Cl and 1737Cl with natural abundances in the approximate ratio of 3:1. Hence, the average atomic mass of chlorine is approximately 35.5 g/mol.

wel

Answer:

The correct option is;

It is used during photosynthesis to capture sunlight

Explanation:

During photosynthesis, light energy from the Sun is converted and stored in sugars as chemical energy. The Sun light energy is used in the formation of complex sugars such as glucose from the combination of water from the ground and carbon dioxide from the atmosphere while oxygen is released as the byproduct. Organisms are then able to obtain energy from the glucose as well as carbon fiber

The chemical equation for the reaction is as follows;

6CO₂     + 12H₂O + light energy → C₂H₁₂O₆  +  6O₂ + 6H₂O

Carbon,     Water,                            GLucose,  Oxygen,   Water
