Answer:
a. 0.4544 N
b. ![5.112 \times 10^{-5 M}](https://tex.z-dn.net/?f=5.112%20%5Ctimes%2010%5E%7B-5%20M%7D)
Explanation:
For computing the normality and molarity of the acid solution first we need to do the following calculations
The balanced reaction
![H_2SO_4 + 2NaOH = Na_2SO_4 + 2H_2O](https://tex.z-dn.net/?f=H_2SO_4%20%2B%202NaOH%20%3D%20Na_2SO_4%20%2B%202H_2O)
![NaOH\ Mass = Normality \times equivalent\ weight \times\ volume](https://tex.z-dn.net/?f=NaOH%5C%20Mass%20%3D%20Normality%20%5Ctimes%20equivalent%5C%20weight%20%5Ctimes%5C%20volume)
![= 0.3200 \times 40 g \times 21.30 mL \times 1L/1000mL](https://tex.z-dn.net/?f=%3D%200.3200%20%5Ctimes%2040%20g%20%5Ctimes%2021.30%20mL%20%5Ctimes%20%201L%2F1000mL)
= 0.27264 g
![NaOH\ mass = \frac{mass}{molecular\ weight}](https://tex.z-dn.net/?f=NaOH%5C%20mass%20%3D%20%5Cfrac%7Bmass%7D%7Bmolecular%5C%20weight%7D)
![= \frac{0.27264\ g}{40g/mol}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B0.27264%5C%20g%7D%7B40g%2Fmol%7D)
= 0.006816 mol
Now
Moles of
needed is
![= \frac{0.006816}{2}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B0.006816%7D%7B2%7D)
= 0.003408 mol
![Mass\ of\ H_2SO_4 = moles \times molecular\ weight](https://tex.z-dn.net/?f=Mass%5C%20of%5C%20H_2SO_4%20%3D%20moles%20%5Ctimes%20molecular%5C%20weight)
![= 0.003408\ mol \times 98g/mol](https://tex.z-dn.net/?f=%3D%200.003408%5C%20mol%20%5Ctimes%2098g%2Fmol)
= 0.333984 g
Now based on the above calculation
a. Normality of acid is
![= \frac{acid\ mass}{equivalent\ weight \times volume}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7Bacid%5C%20mass%7D%7Bequivalent%5C%20weight%20%5Ctimes%20volume%7D)
![= \frac{0.333984 g}{49 \times 0.015}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B0.333984%20g%7D%7B49%20%5Ctimes%200.015%7D)
= 0.4544 N
b. And, the acid solution molarity is
![= \frac{moles}{Volume}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7Bmoles%7D%7BVolume%7D)
![= \frac{0.003408 mol}{15\ mL \times 1L/1000\ mL}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B0.003408%20mol%7D%7B15%5C%20mL%20%5Ctimes%20%201L%2F1000%5C%20mL%7D)
= 0.00005112
=![5.112 \times 10^{-5 M}](https://tex.z-dn.net/?f=5.112%20%5Ctimes%2010%5E%7B-5%20M%7D)
We simply applied the above formulas

Welding, carpentry, masonry, construction worker, barber
Explanation:
The component of a regenerative vapor power cycle that permits only liquid to pass through to a region of lower pressure is a Valve/trap.
<h3>What is vapor?</h3>
- In physics, a substance in the gas phase at a temperature lower than its critical temperature is referred to as a vapor or vapor.
- This means that the vapor can be condensed to a liquid by increasing the pressure on it without decreasing the temperature.
- An aerosol is distinct from a vapor.
- A suspension of minute liquid, solid, or both types of particles in a gas is known as an aerosol.
<h3>Why does vapor form?</h3>
- Evaporation or sublimation are two processes that can be used to create it.
- Unlike clouds, fog, or mist, which are only suspended drops of liquid water in the atmosphere, watevaporur is a gas and cannot be seen.
- In the atmosphere, water vapor frequently exists below the boiling point.
