Answer: 3.79*10^24 atoms
Explanation:
1 mole = 6.02214076*10^23 atoms
Answer:
The pressure is 58.75 atm.
Explanation:
From Vanderwaal's equation,
P = nRT/(V-nb) - n^2a/V^2
n is the number of moles of SO2 = mass/MW = 500/64 = 7.81 mol
R is gas constant = 0.0821 L.atm/mol.K
T is temperature of the vessel = 633 K
V is volume of the vessel = 6.3 L
a & b are Vanderwaal's constant = 6.865 L^2.atm/mol^2 and 0.0567 L/mol respectively.
P = (7.81×0.0821×633)/(6.3 - 7.81×0.05679) - (7.81^2 × 6.865)/6.3^2 = 69.30 - 10.55 = 58.75 atm
Answer:
a) 6.5
b) pressure decreases
c)22 atm
Explanation:
Since the initial volume V1 is 5.40 L and the final volume V2 is 35.1 L, the ratio of V2:V1= 35.1/5.40= 6.5 hence the volume increases by a factor of 6.5.
When the volume increases, the pressure decreases accordingly in accordance with Boyle's law. Boyle's law states that the volume of a given mass of gas is inversely proportional to its pressure at constant temperature.
c) From Boyle's law
Initial volume V1= 5.40 L
Final volume V2= 35.1 L
Initial pressure P1= 143 ATM
Final pressure P2 = the unknown
P1V1= P2V2
P2= P1V1/V2
P2 = 143 × 5.40/ 35.1
P2= 22 atm
Critical pressure is the pressure of a gas or vapor in its critical state and critical point is a point on a phase diagram at which both the liquid and gas phases of a substance have the same density, and are therefore indistinguishable.
