Answer:
100,000 Ozone Molecules
Explanation:
I just found this online calculator that got the answer.
<h2>
Hello!</h2>
The answer is:
The percent yield of the reaction is 32.45%
<h2>
Why?</h2>
To calculate the percent yield, we have to consider the theoretical yield and the actual yield. The theoretical yield as its name says is the yield expected, however, many times the difference between the theoretical yield and the actual yield is notorious.
We are given that:
Now, to calculate the percent yield, we need to divide the actual yield by the theoretical and multiply it by 100.
So, calculating we have:
Hence, we have that the percent yield of the reaction is 32.45%.
Have a nice day!
Answer:
Carbon dioxide is added to the atmosphere by human activities. When hydrocarbon fuels (i.e. wood, coal, natural gas, gasoline, and oil) are burned, carbon dioxide is released. During combustion or burning, carbon from fossil fuels combines with oxygen in the air to form carbon dioxide and water vapor.

Answer:
0.365 m
Explanation:
The <em>definition of molality</em> is:
- molality = moles of solute / kg of solvent
First <u>we calculate the moles of the solute, LiCl</u>. We do so using its <em>molar mass</em>:
- 0.317 g ÷ 42.394 g/mol = 7.48x10⁻³ mol
Then we calculate the mass of the solvent, water. We do so using its <em>density</em>:
- 20.5 mL * 0.9982 g/mL = 20.5 g
- 20.5 g / 1000 = 0.0205 kg
Finally we <u>calculate the molality of the solution</u>:
- 7.48x10⁻³ mol / 0.0205 kg = 0.365 m
