<h2>Hello!</h2>

The answer is:

The third option, 79.8%

<h2>Why?</h2>

To calculate the percent yield we need to divide the actual yield by the theoretical yield, and then, multiply it by 100 in order to find the percent.

So, we from the statement we know the following information:

ActualYield=220.0g\\TheoreticalYield=275.6g

Let's use the following formula and substitute the given information:

PercentYield=\frac{ActualYield}{Theoretical}*100\\\\

PercentYield=\frac{220g}{275.6g}*100=0.798*100=79.8(percent)

Hence, we have that the correct option is the third option, the percent yield is 79.8%.

Have a nice day!

A gas cylinder initially contains 463 L of gas at a pressure of 159 atm. If the final volume of gas is 817 L, what is the final
Agata [3.3K]

Answer:

The final pressure is 90.1 atm.

Explanation:

Assuming constant temperature, we can solve this problem by using <em>Boyle's Law</em>, which states:

  • P₁V₁=P₂V₂

Where in this case:

  • P₁ = 159 atm
  • V₁ = 463 L
  • P₂ = ?
  • V₂ = 817 L

We <u>input the given data</u>:

  • 159 atm * 463 L = P₂ * 817 L

And <u>solve for P₂</u>:

  • P₂ = 90.1 atm

The final pressure is 90.1 atm.
