Answer:D) It is less than the total mass of glucose and oxygen formed.
Explanation: During photosynthesis, six molecules of water reacts with six molecules of carbon dioxide to form one molecule of glucose and six molecules of oxygen. The balanced equation for the reaction is 6H2O + 6CO2 --> C6H12O6+ 6O2.
In writing chemical equations, the mass of the reactants must be equal to the mass of the products because according to the law of conservation of mass states that matter can neither be created nor be destroyed in an ordinary chemical reaction. The mass of carbon dioxide and water must be equal to the mass of glucose and oxygen formed. Therefore, the mass of carbon dioxide used during photosynthesis is less than the mass of glucose and oxygen formed.
