Answer: Answer is D, water
Explanation: Water is the correct option among all and other options like sugar, oxygen and ATP are the products of the photosynthesis. Water is required along with other reactants to produce these products.
The mass of water produced by the reaction of the 23 g of 
is 13.8 g.
The given chemical reaction;
In the given compound above, we can deduce the following;
- molecular mass of = 28 + (2 x 16) = 60 g
- molecular mass of
= 2(18) = 36 g
60 g of --------- 36 g of water
23 g of ------------- ? of water
Thus, the mass of water produced by the reaction of the 23 g of is 13.8 g.
