Hello!</h2>
The answer is: Charle's Law.
<h2>
Why?</h2>
The law that states that the volume and absolute temperature of a fixed quantity of gas (ideal gas) are proportional under constant pressure is the Charle's Law, also known as the law of volumes.
The law describes how a gas kept under constant pressure tends to expand when the temperature increases and it's described by the following equation:
![\frac{V}{T}=k](https://tex.z-dn.net/?f=%5Cfrac%7BV%7D%7BT%7D%3Dk)
Where,
![V=Volume\\T=Temperature\\k=constant](https://tex.z-dn.net/?f=V%3DVolume%5C%5CT%3DTemperature%5C%5Ck%3Dconstant)
Also, to describe the relationship between two differents volumes at different temperatures, we have:
![\frac{V_{i}}{T_{i}}=\frac{V_{f}}{T_{f}}](https://tex.z-dn.net/?f=%5Cfrac%7BV_%7Bi%7D%7D%7BT_%7Bi%7D%7D%3D%5Cfrac%7BV_%7Bf%7D%7D%7BT_%7Bf%7D%7D)
Where,
![V_{i}=InitialVolume\\T_{i}=InitialTemperature\\V_{f}=FinalVolume\\T_{f}=FinalTemperature](https://tex.z-dn.net/?f=V_%7Bi%7D%3DInitialVolume%5C%5CT_%7Bi%7D%3DInitialTemperature%5C%5CV_%7Bf%7D%3DFinalVolume%5C%5CT_%7Bf%7D%3DFinalTemperature)
Have a nice day!

Explanation:
First, I'm assuming you have a reaction of mercury(II) oxyde descomposition. If this is the case, then the equation to use is the following:
HgO ---------> Hg + O2
Balancing the equation:
2HgO ----------> 2Hg + O2
This means that 2 moles of HgO reacts to produce 1 mole of O2, so, we first calculate the moles of O2, then, the moles of HgO and finally the mass:
We have the volume of O2, the pressure and temperature, so let's use the ideal gas equation:
PV = nRT
Solving for n:
n = PV/RT
R: 0.082 L atm / K mole
T = 70 + 273 = 343 K
V = 83 / 1000 = 0.083 L
Calculating n:
n = 1 * 0.083 / 0.082 * 343
n = 0.003 moles
as stated before, 2 moles of HgO reacts with 1 mole of oxygen so:
2 moles HgO = 1 moles O2
moles HgO = moles O2 / 2
moles HgO = 0.003 / 2 = 0.0015 moles
Finally, to calculate the mass:
m = n * MM
the molar mass of HgO is 216.59 g/mol, so replacing:
m = 0.0015 * 216.59
m = 0.3249 g
Answer:
The correct answer is - right-side up.
Explanation:
A diverging mirror is a curved mirror that can be bulge outside towards the source of light called a convex mirror or inward away from the source of light called a concave mirror.
A convex mirror is a mirror that forms an image bigger and but right side up or exact as the object direction also called a virtual image. It appears to be bigger than the real object and not upside down as concave mirrors.
