Answer: dna genes chromosomes nucleus
Explanation:
Answer is: c. 1.204 × 10²⁴ atoms
of carbon.
n(C) = 2 mol; amount of substance of carbon.
Na = 6.02·10²³ 1/mol; Avogadro constant (the number of constituent particles, in this example atoms, that are contained in the amount of substance given by one mole).
N(C) = n(C) · Na.
N(C) = 2 mol · 6.02·10²³ 1/mol.
N(C) = 12.04·10²³ = 1.204·10²⁴; number of carbon atoms in a sample.
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.
