When we look at the periodic table, it tells us the Sodium is labeled as 'Na'.
Answer : The pressure of the gas using both the ideal gas law and the van der Waals equation is, 60.2 atm and 44.6 atm respectively.
Explanation :
First we have to calculate the pressure of gas by using ideal gas equation.
where,
P = Pressure of 
gas = ?
V = Volume of gas = 0.805 L
n = number of moles = 1.93 mole
R = Gas constant = 
T = Temperature of gas = 306 K
Now put all the given values in above equation, we get:
Now we have to calculate the pressure of gas by using van der Waals equation.
P = Pressure of gas = ?
V = Volume of gas = 0.805 L
n = number of moles = 1.93 mole
R = Gas constant =
T = Temperature of gas = 306 K
a = pressure constant = 
b = volume constant = 
Now put all the given values in above equation, we get:
![(P+\frac{(4.19L^2atm/mol^2)\times (1.93mole)^2}{(0.805L)^2})[0.805L-(1.93mole)\times (5.11\times 10^{-2}L/mol)]=1.93mole\times (0.0821L.atm/mol.K)\times 306K](https://tex.z-dn.net/?f=%28P%2B%5Cfrac%7B%284.19L%5E2atm%2Fmol%5E2%29%5Ctimes%20%281.93mole%29%5E2%7D%7B%280.805L%29%5E2%7D%29%5B0.805L-%281.93mole%29%5Ctimes%20%285.11%5Ctimes%2010%5E%7B-2%7DL%2Fmol%29%5D%3D1.93mole%5Ctimes%20%280.0821L.atm%2Fmol.K%29%5Ctimes%20306K)
Therefore, the pressure of the gas using both the ideal gas law and the van der Waals equation is, 60.2 atm and 44.6 atm respectively.
The first one because some people might not believe that and others might believe that.
The Mesosaurus could not swim between the continents in the open ocean, so the fossils show that the continents must have been together in the past.
Explanation:
One critical point in the use of Mesosaurus to explain continental drift is that they could not swim between the continents in open ocean.
Mesosaurus is known as middle lizard and its fossils have been used to proof that continental drifts truly result. Alfred Wegener is credited with the hypothesis of continental drift in which the land masses where once joined together.
- The fossils of this ancient organism have been discovered in the Southern part of Africa and Eastern part of South America.
- Both continents were once believed to be joined together in geologic time past.
- Mesosaurus was a swamp dwelling animal that could not have swim between the two continents. The ocean will pose a barrier. For its fossils to be found on the two continents, the land masses must have been joined together.
