24 molecules of H2O are needed by the plant to produce 4 molecules of sugar.
<h2>What is
photosynthesis?</h2>
The process by which plants convert carbon dioxide, water, and sunlight into oxygen and sugar-based energy is known as photosynthesis.
<h3>The photosynthesis equation is as follows:</h3>
6CO2 + 6H2O + Sunlight → C6H12O6 + 6O2
The following three significant activities are involved in photosynthesis:
1. Chlorophyll absorbs light energy.
2. Water molecules are divided into hydrogen and oxygen and light energy is converted to chemical energy.
3. Carbon dioxide is converted to sugars.
Therefore, a plant needs four molecules of H2O and four molecules of CO2 to make one molecule of glucose or sugar, hence a plant needs 24 molecules of H2O and 24 molecules of CO2 to make four molecules of sugar.

Answer:
Protons
Explanation:
Protons are the subatomic particle that determines the identity of an element.
I think C-I
It can also be wrong but that’s my opinion
Explanation:
At each reflecting surface (benzene and glass) there will be 180 degree phase change.
Now, for constructive interference the optical path in benzene is 
.
Formula to calculate thickness of a benzene thin film is as follows.
Optical path length through benzene () = 
Hence, substituting the given values into the above formula as follows.
Optical path length through benzene =
d = 
= 
= 
(as 1 nm = 
= 204.9 m
Thus, we can conclude that minimum thickness of benzene is 204.9 m.
