According to this formula when:
ΔG = ΔH - TΔS = 0
∴ ΔS = ΔH/T
∴ ΔS = n*ΔHVap / Tvap
- when n is the number of moles = mass/molar mass
when the mass = 24.1 g
and the molar mass = 187.3764 g/mol
by substitution:
∴ n = 24.1 / 187.3764g/mol
= 0.129 moles
and ΔHvap is the molar enthalpy of vaporization is 27.49 kJ/mol
and Tvap is the temperature in Kelvin = 47.6 + 273 = 320.6 K
So by substitution, we will get the ΔS the change in entropy:
∴ΔS = 0.129 mol * 27490 J/mol / 320.6 K
= 11 J/K
Answer:
The average atomic mass of an element is the sum of the masses of its isotopes, each multiplied by its natural abundance (the decimal associated with percent of atoms of that element that are of a given isotopе). An element does not have an absolute atomic mass.

I believe the correct answer from the choices listed above is option D. The modern atomic model is sometimes called the electron cloud or quantum mechanics model. It <span>uses complex shapes of orbitals (sometimes called electron clouds), volumes of space in which there is likely to be an electron. </span>
Hope this answers the question. Have a nice day.
Answer : 10 plague hearts are there in one map at a time in state of decay 2
Explanation : The State of Decay 2 consists of 10 Plague Hearts which one needs to destroy and they are placed on randomly dotted areas around the map inside a searchable location on it.
With each heart that one destroys, the remaining other ones become a little bit tougher and are more heavily guarded by the undead people.
