The law of conservation of mass<span> states that in a chemical reaction, </span>mass<span> is neither created nor destroyed. That means, the total </span>mass for<span> the reactants needs to equal the total </span>mass<span> of the products. The reactants </span>for<span> photosynthesis are 6 carbon dioxide, 6 water and sunlight.</span>
