Answer:
49902.4 g/mol.
Explanation:
Using ideal gas equation,
PV = nRT
Where,
P = pressure
= 0.00144 atm
V = volume
= 0.01 l
T = absolute temperature
= 273 + 23.5
= 296.5 K
R = gas constant
= 0.0821 atm.l/K.mol
n = number of moles
n = (0.00144 * 0.01)/0.0821 * 296.5
= 5.92 x 10^-7 mol.
Molar mass = mass/number of moles
= 0.02952/5.92 x 10^-7
= 49902.4 g/mol.
<span>star is born when clouds of dust and elements are gathered together in a certain space due to gravity, more and more mass and therefore pressure builds. when the pressure becomes enough to overcome the electronic repulsive force between two hydrogen nuclei, they are forced together and massive amounts of energy are given off forming helium atoms. this energy is then used to fuse other nuclei together. this could be compared to the way human life starts, where instead of 2 nuclei joining together to start a life cycle, two gametes, or sex cells are joined together. </span>
5.2/ 24.3 = 0.214
0.214 x 2 = 0.428
0.428 x 36.5= 15.6g
The mercury (Hg) has 80 electrons. The electrons are distributed in the s, p, d and f orbitals. The electronic configuration of Hg can be shown as-. We can see that there are two filled d-orbitals 3d and 4d. There is only one filled f orbital which is 4f. The electron cloud of the s, p, d and f are different due to their different screening and penetration effect towards the nucleus. The electron cloud of f-orbital is most diffuse than the other three. The outermost electrons of mercury is , which is its valence electrons i.e. (+2).
