You would have to use the ideal gas law: PV = nRT where,
P = pressure
V = volume
n = moles
R = universal gas constant for a specific pressure (in this case it's 62.364 torr)
T = temperature in Kelvin
First, convert Celsius to kelvin by adding 273 to 25, which gives you 298K
Now plug in your variables to find n:
(800 torr)(1.25 L) = n(62.364)(298K)
1000 = 18584.472n
Now divide 1000 by 18584.472 to get n:
1000/18584.472 = 0.054 moles

Answer:
Limiting reactant= SO₂, Theoretical yield = 9.6g SO₃
Explanation:
The first step is is to find the limiting reactant; you do this using stoichiometry.
The reactant that produces the smallest amount of sulfur trioxide SO₃, is the limiting reactant.
In this problem, SO₂ is the limiting reactant.
Now to find the theoretical yield we will use the smallest value of SO₃.
I have uploaded a picture to better illustrate the problem and hope it helps.
I believe the best reason as for why carbon is the basis of organic chemistry would be D. Carbon can bond with hydrogen.
