Answer:
It is greater than the mass of oxygen formed.
Explanation:
<em>Photosynthesis</em> is the process of using light energy to convert carbon dioxide and water to glucose and oxygen.
6CO₂ + 6H₂O ⟶ C₆H₁₂O₆ + 6O₂
Mass of CO₂ + H₂O = mass of C₆H₁₂O₆ + 6O₂
Subtract the mass of glucose from the right-hand side but not the left. Then
Mass of CO₂ + H₂O > mass of O₂
A is <em>wrong</em>, because glucose is <em>formed</em>, not used.
Bb is <em>wrong</em>, because oxygen is <em>formed</em>, not used.
C is <em>wrong</em>, because the total mass of reactants is <em>greater than</em> just one of the products.

Explanation:
Answer:
3.59x10^21 molecules
Explanation:
1mole of a substance contains 6.02x10^23 molecules.
Therefore, 1mole of C8H18 will also contain 6.02x10^23 molecules
1mole of C8H18 = (12x8) +(18x1) = 96 + 18 = 114g.
1mole (i.e 114g) oh C8H18 contains 6.02x10^23 molecules.
Therefore, 0.68g of C8H18 will contain = (0.68 x 6.02x10^23)/114 = 3.59x10^21 molecules
