Moles of O₂ = 3.92
<h3>Further explanation</h3>
Given
V=1 L
T=-118 °C + 273 = 155 K
P = 49.77 atm
Required
moles of O₂
Solution
the gas equation can be written
where
P = pressure, atm
V = volume, liter
n = number of moles
R = gas constant = 0.08206 L.atm / mol K
T = temperature, Kelvin
Input the value :
n= PV/RT
It could be a lump of coal.
Since you can break pieces off, maybe charcoal ... the real thing, not a "briquet".
Do your hands get all black when you handle it ?

Lewis structure for CHCl3
Ans:
It is also known as law of multiple proportion. It states that if two elements form more than one compound between them then the ratios of the masses of the second element which combine with the fixed mass of first element will be ratios of small whole numbers.
