Answer:
The answer to your question is n = 6.24 moles
Explanation:
Data
Volume = 150 l
moles = ?
Temperature = 20°C
Pressure = 1 atm
R = 0.082 atm L / mol°K
Process
1.- Convert temperature to °K
T = 20 + 273 = 293°K
2.- Use the formula of ideal gases
Formula
PV = nRT
-Solve for n
n = PV/RT
-Substitution
n = (1)(150) / (0.082)(293)
-Simplification
n = 150 / 24.026
-Result
n = 6.24 moles
Answer:
k
Explanation:
electron affinity (EA) depends on various factors like effective nuclear charge (enc) , size of the atom, ellipticity of sub-shell (ep) , nature of configuration.
more is the enc more will be the EA
more is the size less will be the EA
more valance shell ellipticity (closer to the nuclei) more will the EA ( all given element posses P orbital in the valance shell)
