Explanation:
Formula for compressibility factor is as follows.
z =
where, z = compressibility factor for helium = 1.0005
P = pressure
= molar volume
R = gas constant = 8.31 J/mol.K
T = temperature
So, calculate the molar volume as follows.
=
= 0.0056
As molar mass of helium is 4 g/mol. Hence, calculate specific volume of helium as follows.
=
= 0.00139
= 0.00139
= 1.39
Thus, we can conclude that the specific volume of Helium in given conditions is 1.39 .
Explanation:
The Lewis dot diagram shows how electrons participate in a bond with Carbon and Chlorine. This is shown by the sticks and the 2 paired electrons near the carbon atom which represent the bonds. These electrons form these bonds because they form octets when they are bonded which most molecules and compounds follow

5.5 litres is the volume of chlorine gas at 38oC and 1.63 atm is needed to react completely with 10.4 grams of sodium to form sodium chloride.
Explanation:
data given:
mass of sodium chloride in reaction = 10.4 grams
atomic mass of one mole of NaCl = 58.44 grams/mole
balanced equation for the reaction:
2Na (s) + Cl2 (g) 2NaCl (s).
number of moles =
=
= 0.17 moles of Na in the reaction.
from the reaction,
2 moles of Na reacted with 1 mole of Cl2
0.17 moles of Na reacted with x moles
=
x = 0.35 moles of chlorine gas reacted to form NaCl
To know the volume following equation will be used:
PV = nRT
V = R=0.0826 L atm/Mole.K, T = 311.15, P= 1.63 atm, n= 0.35 moles
V =
V = 5.5 litres is the volume of chlorine gas formed at given conditions.
