Answer:
Explanation:
Here, we want to calculate the number of moles of methane in the container
From the ideal gas law:
where:
P is the pressure inside the container which is 3 atm
V is the volume of the container which is 2 L
R is the molar gas constant which is 0.0821 Latm/mol.k
T is the temperature in Kelvin (we convert the temperature in Celsius by adding 273 : 273 + 77 = 350 K)
n is the number of moles that we want to calculate
Substituting the values, we have it that:
They generally have 4 - 7 electrons in their outer shell.
<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:
Let's use the following formula and substitute the given information:
Hence, we have that the correct option is the third option, the percent yield is 79.8%.
