Answer:
Option (3) is the correct answer.
Explanation:
Dinitrogen tetroxide decomposes to give nitrogen dioxide according to equation below
N2O4--->2NO2
According to avogadros law
1 moles =22.4 l
what about 2.45 l
=2.45l x1 mole/22.4=0.1094 moles
by use of reacting ratio that 1 :2
the moles of No2 = 0.1094 x2=0.2188 moles
1 moles= 22.4 l
what about 0.2188moles
=(0.2188moles x22.4 l) /1moles=4.90 L

Boyle's law :- the pressure (p) of a given quantity of gas varies inversely with its volume (v) at constant temperature.
Boyle's law can also be formularized as P1V1 = P2V2
Charle's law :- the volume occupied by a fixed amount of gas is directly proportional to its absolute temperature, if the pressure remains constant.
Charle's law can also be formularized as V1/T1 = V2/T2
Most of the elements in the periodic table are METALS........
There are two electrons in 4s and 6 in 3d. When you lose 3 electrons, you will be left with an ion of 3+ charge!
