Answer:
Thanks. Can I have brainliest pls. I am trying to reach a goal. I sent you a friend request.
Explanation:
No way that is a real question you have to answer.
Answer:
9/22 or 40.9%
Explanation:
Probability describes the likelihood of an event. To find simple probability, like in this question, use division.
To find the probability of the first question being a free response, you first need to find the total number of questions. This can be done by adding together all of the given information. There are 10 multiple choice, 3 essays, and 9 free responses.
This means that there are 22 total questions. Next, find how many of these questions are free-response. We know that there are 9 free responses and 22 questions in total. So, 9 out of 22 are free responses. This can be rewritten as 9/22.
If you want to find the percentage, simplify the fraction and convert it to a percentage.
Then, move the decimal 2 places to the right. This gives you 40.9%, which is the probability of the first question being a free-response.
If the pressure, volume, and temperature are 202650 Pa, 0.004 cubic meters, and 400.15 K. Then the number of the mole is 0.24 mol.
<h3>What is thermodynamics?</h3>
It is a branch of science that deals with heat and work transfer.
We know that the Ideal gas equation is given as
PV = nRT
Where
P = Pressure (Pa)
V = Volume (in m³)
n = Number of moles (mol)
R = universal gas constant (8.314 J⋅K⁻¹⋅mol⁻¹)
T = temperature (in K)
We have
P = 2 atm = 202.65 × 10³ Pa
V = 4 liters = 0.004 m³
T = 127 °C = 400.15 K
Then we have
Then the number of the mole will be
