Answer:
Carbon dioxide is used up, and oxygen is produced.
Explanation:
For photosynthesis to occur the plant need carbon dioxide water and sunlight to convert it into glucose for it to eat and oxygen is a byproduct of the chemical reaction.
Mass NaCl = 4.348
Mass solution = 21.040 - 4.348 = 16.692
mass/mass % =
4.348/16.692
= 26%
mass/vol % =
21.7%
Molecular mass of NaCl = 58.5
Moles of NaCl = 0.074
Volume of solution = 0.02 L
Molarity = 3.7 mol/Liter
