Answer:
Most viscous to least viscous: ![(c)> (b)> (a)](https://tex.z-dn.net/?f=%28c%29%3E%20%28b%29%3E%20%28a%29)
Explanation:
For hydrocarbons, viscosity increases with increasing molar mass. Because increasing molar mass signifies increase in number of electrons in molecules.
We know that in non-polar hydrocarbons, only van der waal intermolecular force exists. Van der waal force is proportional to number of electrons in a molecule.
Therefore with increasing molar mass, van der waal force increases. hence molecules gets more tightly bind with each other resulting increase in viscosity.
Here molar mass order : ![(c)> (b)> (a)](https://tex.z-dn.net/?f=%28c%29%3E%20%28b%29%3E%20%28a%29)
Therefore viscosity order : ![(c)> (b)> (a)](https://tex.z-dn.net/?f=%28c%29%3E%20%28b%29%3E%20%28a%29)
Answer:
The volume of the gas is 89.60
Explanation:
When converting from moles to volume, you would multiply by 22.4 because 1 mole equals 22.4 liters at STP.
So...
4.0 moles * 22.4 liters =
89.60 liters
