A gas occupies 1.15 L at standard pressure and temperature and 1.56 L at 317 K and 650 mmHg, assuming ideal behavior.
<h3>What is an ideal gas?</h3>
An ideal gas is a gas whose behavior can be explained through ideal gas laws. One of them is the combined gas law.
A gas occupies 1.15 L (V₁) at STP (T₁ = 273,15 K and P₁ = 760 mmHg). We can calculate the temperature (T₂) at which V₂ = 1.56 L and P₂ = 650 mmHg, using the combined gas law.

Answer:
The correct option is: D. A suspension
Explanation:
A suspension is a type of heterogeneous mixture in which solid particles are suspended through out the bulk of the solvent through mechanical agitation. The solid phase is also known as the internal phase and the solvent is known as external phase. In a suspension, the solid particles are generally larger than one micrometer and thus are unable to dissolve in the medium. The solid particles of a suspension are large enough to get precipitated.
<u>Therefore, in the given situation, the chicken broth is </u><u>a suspension</u><u> </u>as the contents or solid particles of the container needs to be suspended in the solvent by shaking to prevent sedimentation.

Atomic weight is Ar of the atom (what you see on the periodic table)
atomic weight<span> is relative </span>atomic mass, so yeah same thing
<span>Technically, this question is badly worded. If all 4 containers were at STP, then all 4 containers would have the same pressure. So I'll assume instead that all 4 containers are at the same temperature, and then use the ideal gas law to determine the relative internal pressures of each container.
The idea gas law is
PV = nRT
where
P = Pressure
V = Volume
n = number of moles
R = Ideal gas constant
T = Absolute temperature
Since all the containers are at the same temperature, we can ignore the R and T parts of the formula and substitute some value K for constant. So we get
PV = nK
Now solve for P
PV = nK
P = nK/V
From the above, you can see that the pressure is proportional to the number of moles divided by the volume. So let's calculate that value for each container.
Container A: 0.5 / 11.2 = 0.044642857
Container B: 2 / 22.4 = 0.089285714
Container C: 1 / 22.4 = 0.044642857
Container D: 2 / 11.2 = 0.178571429
So as you can see, the pressures in containers A and C are the same, which is the first available option, so you are correct.</span>
