Answer:
SO < CO2 < C3H8
Explanation:
Entropy refers to the degree of disorderliness of a system. The standard molar entropy of a substance refers to the entropy of 1 mole of the substance vunder standard conditions.
The molar entropy depends on the number of microstates in the system which in turn depends on the number of atoms in the molecule.
C3H8 has 11 atoms and hence the highest number of microstates followed by CO2 having three atoms and least of all SO having only two atoms.
No units are provided in the data table, though one would usually assume that 0.244 is molarity of NaOH, and buret data of 14.7 is probably the final volume of NaOH in mL. No identification is given for the 38, but maybe this is the initial buret volume in mL.
If the buret was rinsed with water, it should have been left to dry for some time, or else the added water may slightly dilute the NaOH solution placed in it.
1 mol of carbon 12 would possess 6.02 X 10^23 carbon atoms.
I think you forgot to add some of the question
The movement of gases through pinhole is called effusion and the effusion rate indirectly proportional to the molar mass of gas
The lighter mass gas effuses faster than the heavier one
so He(g) will escapes faster and it will move with higher average speed because it has less mass than Ne(g)
