Hello!
This question requires a model -- you'll have to do that yourself. However, I can explain the steps for the process:
• Chlorophyll absorbs the sun's energy.
• The energy is used to split water molecules into hydrogen and oxygen.
• The oxygen is released from the leaves into the atmosphere.
• The hydrogen and carbon dioxide glucose (food) for plants.

Answer:
the total density of the mixture = 3.415 x 10^3 g/mL
Explanation:
given:
density of a substance is 3.4 x 10^3 g/mL
Mixing it with another substance increases the density by 1.5 x 10^1 times.
find:
What is the density of the mixture?
-------------------------------------------------
let density (a) = 3.4 x 10^3 g/mL
density(b) = 1.5 x 10^1 g/mL
since there is no specific density provided for the mixture, we then add both to increase the density,
total density = density(a) + density(b)
total density = 3.4 x 10^3 g/mL + 1.5 x 10^1 g/mL
total density = 3.415 x 10^3 g/mL
therefore,
the total density of the mixture = 3.415 x 10^3 g/mL

Solubility :Solubility can be define as the amount of a substance that dissolves or mixes in a given amount of solvent at specific conditions.
Solubility equilibrium
Ksp = ![[A^{+} ]^{a}](https://tex.z-dn.net/?f=%5BA%5E%7B%2B%7D%20%5D%5E%7Ba%7D)
![[B^{-} ]^{b}](https://tex.z-dn.net/?f=%5BB%5E%7B-%7D%20%5D%5E%7Bb%7D)
Ksp = solubility product constant
A+ = cation in an aquious solution
B- = anion in an aqueous solution
a, b = relative concentrations of a and b
Given,
Solubility = s = 3.60 × 
g/L
molar mass = 288 g/ mol
∴ s= 3.60 × g/L ÷ 288 g/ mol = 1.25 ×

∴ =![[s]^{} [3s]^{3}](https://tex.z-dn.net/?f=%5Bs%5D%5E%7B%7D%20%5B3s%5D%5E%7B3%7D)
∴ = 3 
∴ = 3 × (3.60 × 
∴ = 503.8848 ×
= 5.04 ×
