Answer:
27.06 mL.
Explanation:
- Firstly, we need to calculate the molarity of acrylic acid.
Molarity is the no. of moles of solute dissolved in a 1.0 L of the solution.
M = (no. of moles of acrylic acid)/(V of the solution (L))
M = (mass/molar mass)acrylic acid / (V of the solution (L))
mass of acrylic acid = 0.0975 g, molar mass of acrylic acid = 72.06 g/mol, V of the solution = 250 mL = 0.25 L.
∴ M = (0.0975 g/72.06 g/mol)/(0.25 L) = 0.0054 M.
- For the acid-base neutralization, we have the role:
The no. of millimoles of acid is equal to that of the base at the neutralization.
<em>∴ (XMV) NaOH = (XMV) acrylic acid.</em>
X is the no. of reproducible H⁺ (for acid) or OH⁻ (for base),
M is the molarity.
V is the volume.
X = 1, M = 0.05 M, V = ??? mL.
X = 1, M = 0.0054 M, V = 250.0 mL.
∴ V of NaOH = (XMV) acrylic acid/(XM) NaOH = (1)(0.0054 M)(250.0 mL)/(1)(0.05 M) = 27.06 mL.
Answer: Transpiration is a process process in which plants absorb the water through their roots and then release it in the form of water vapour through small pores located in the leaves of the plants.
Explanation:
Transpiration is very important for the life in our planet.
Transpiration is define as a process in which plants absorb the water through their roots and then release it in the form of water vapour.
The process of transpiration occurs through small pores which are located in the leaves of the plants.
Therefore, this process is essential to cool plants and it helps them to mantain their temperature.
The rate of transpiration depends on the following factors:
1. The humidity.
2. The light.
3. The temperature.
4. Water in the soil.
5. Wind.
6. Soil water.
The solubility of nitrogen gas in water is 1.90 mL/dL at 1.00 atm and 13.3 mL/dL at 7.00 atm.
We want to relate the solubility of a gas with its partial pressure.
We can do so using Henry's law.
<h3>What does Henry's law state?</h3>
Henry's law states that the amount of dissolved gas in a liquid is proportional to its partial pressure above the liquid.
C = k × P
where,
- C is the concentration of a dissolved gas.
- k is the Henry's Law constant.
- P partial pressure of the gas.
The solubility of nitrogen gas is 1.90 mL/dL of blood at 1.00 atm.
Since the solvent is basically water, we can understand that the concentration of nitrogen gas is 1.90 mL/dL at 1.00 atm.
We can use this information to calculate Henry's Law constant.
k = C/P = (1.90 mL/dL)/1.00 atm = 1.90 mL/dL.atm
We want to calculate the solubility of nitrogen gas at a pressure of 7.00 atm.
We will use Henry's law.
C = k × P = (1.90 mL/dL.atm) × 7.00 atm = 13.3 mL/dL
The solubility of nitrogen gas in water is 1.90 mL/dL at 1.00 atm and 13.3 mL/dL at 7.00 atm.
