The Dilution of a buffer solution with a small amount of water will raise the PH of the solution. Dilution is the process of "reducing the concentration of a solute in a solution by simply adding more solvent to the solution, such as water." Dilution involves increasing the amount of solvent in a solution without increasing the amount of solute.
When a solvent is added, the concentration of the solute in the solution is diluted. By removing the solvent, concentration raises the solute concentration in the solution. Dilution is the process of lowering a given solute's concentration in its solution.

The rate of diffusion change would increase if the PO₂ in the capillaries was 40 mmHg and the PO₂ in the muscle cell changed from 40 to 20 mmHg.
Simple diffusion is the movement of molecular substances from a region of higher concentration to lower concentration. The mechanism with which the movement of O₂ travels from the blood to the body tissues takes place with the use of simple diffusion.
Now, if PO₂ changes from 40 → 20 mmHg in the muscle cells, and the PO₂ in the blood = 40mmHg. It implies that the pressure gradient(P) has increased. As such, there is an increase in the rate of diffusion of oxygen from the blood to muscle cells.

Answer:
1.306 × 10^24 formula units.
Explanation:
The chemical equation of this qkrstios as follows:
Fe + 2H2O → FeO2 + 2H2
Based on the reaction, 2 mole of H2O produces 1 mole of FeO2
Using the formula as follows;
Mole = mass/molar mass
Molar mass of H2O = 1(2) + 16 = 18g/mol
mole = 78/18
mole = 4.33moles
If 2 mole of H2O reacts to produce 1 mole of FeO2
4.33 moles of H2O will produce 4.33/2 = 2.17moles of FeO2.
To convert moles to formula units, we multiply number of moles by Avagadro number (6.02 × 10^23 units)
= 2.17 moles × 6.02 × 10^23 units
= 13.06 × 10^23
= 1.306 × 10^24 formula units.
