The correct answer is 42. I know this answer is right because i have already turned my assignment in and got it right.
Moles = n = 3.91 mol
Pressure = P = 5.35 atm
Temperature = T = 323 K
Volume = V = ?
Formula used: Ideal Gas Equation is used,
P V = n R T
Solving for V,
V = n R T / P
Putting Values,
V = (3.91 mol × 0.0825 atm.L.mol⁻¹.K⁻¹ × 323 K) ÷ 5.35 atm
V = 19.36 L
T is important to go through a fluid phase as it is being produced because the object must go through heat to be melted and then it should be put into a mold to be formed. Also, it go though heat to keep it from cracking and go to be cooled and harden.

The pressure of 2.29 atm can be converted to 
<h3>What is conversation?</h3>
Conversation is a way of writing a value in another unit, it helps to reduce large values by using a unit.
It should be noted that 1 atm. =760.0 mm Hg
We were given 2.29 atm, the we can convert it to mm Hg. as;
![[ 2.29 atm* 760.0 mmHg / atm.]](https://tex.z-dn.net/?f=%5B%202.29%20atm%2A%20760.0%20mmHg%20%2F%20atm.%5D)
= 1740.4 mm Hg.
Therefore, The pressure of 2.29 atm can be converted to
