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.
Answer & Explanation:
Los electrones externos se encuentran más lejos del núcleo. El número de electrones en la capa más externa (electrones de valencia) de un átomo en particular determina su reactividad (tendencia) a formar enlaces químicos con otros átomos.
Los electrones internos son los más cercanos al núcleo. Protegen los electrones de valencia del núcleo, reduciendo la carga nuclear efectiva.

The redshift<span> of distant </span>galaxies<span> means that the Universe is probably </span>expanding. If we then go back far enough in time, everything must have been squashed together into a tiny dot and the rapid eruption from this tiny dot was the Big Bang. Another piece of evidence could be that because light takes a long time to travel across the Universe, when we look at very distant galaxies or stars we are also looking back in time. This shows us that galaxies a long time ago were quite different from those today, showing that the Universe has changed. This fits better with the Big Bang theory than the Steady State theory
