The temperature of the nitrogen gas is 292.5 K.
<u>Explanation:</u>
Given that
Moles of Nitrogen, n = 5 mol
Volume, V = 30 L
Pressure, P = 4 atm
Gas Constant, R = 0.08205 L atm mol⁻¹ K⁻¹
Temperature = ? K
We have to use the ideal gas equation,
PV = nRT
by rearranging the equation, so that the equation becomes,
T = 
Plugin the above values, we will get,
T = 
= 292.5 K
So the temperature of the nitrogen gas is 292.5 K.
C) energy level
Looking at quantum mechanics, we see that electrons exist at certain energy levels. When they get excited, they’ll jump from one energy state to a higher energy state and down. We can the. Look at the color it admits and determine what the energy level is.
Avagadros number is where 1 mol of any substance is made of 6.022 x 10²³ units. These units could be atoms making up an element of molecules making up a compound.
1 mol of Br₂ is made of 6.022 x 10²³ molecules of Br₂
the flask contains 0.100 mol
Therefore if 1 mol has 6.022 x 10²³ molecules of Br₂
then 0.1 mol has - 6.022 x 10²³ molecules/mol x 0.1 mol
therefore number of molecules - 6.022 x 10²² Br₂ molecules ₂
