First calculate the mole fraction of each substance:
Acetone: 2.88 mol ÷ (2.88 mol + 1.45 mol) = 0.665
Cyclohexane: 1.45 ÷ (2.88 mol + 1.45 mol) = 0.335
Raoult's Law: P(total) = P(acetone) · χ(acetone) + P(cyclohexane) · χ(cyclohexane).
P(total) = 229.5 torr · 0.665 + 97.6 torr · 0.335
P(total) = 185.3 torr
χ for acetone: 229.5 torr · 0.665 ÷ 185.3 torr = 0.823
χ for cyclohexane: 97.6 torr · 0.335 ÷ 185.3 torr = 0.177
Explanation:
More is the intermolecular forces present between the molecules of a substance more will be the boiling point of the substance.
Since, water is able to form hydrogen bonding and it also have dipole-dipole interaction as these are stronger than the forces present in ammonia. Hence, boiling point of water is greater than the boiling point of .
In , there are only dispersion forces present in it and these forces are weakest intermolecular forces.
As a result, the enthalpies of vaporization of the following substances increase in the order .
Answer:
Another name for ethanol can be ethyl alcohol, drinking alcohol or commonly called as alcohol.
Explanation:
The Ethanol is a simple alcohol which responds to this formula C2H6O.
You can also writes it as C2H5OH and as CH3-CH2-OH.
It is the principal active ingredient found in alcoholic drinks (for example in beer,vine,whisky,etc).
It is a volatile,flammable and colorless liquid.
1. The third option is the least soluble in water because it is the chain with the most number of hydrocarbons. Next is the second option while the first one is the most soluble.
2. Statements 1 and 2 are true. The third option is not true all the time because it depends on the structure of the compound.
Answer:
Molar volume at STP can be used to convert from moles to gas volume and from gas volume to moles. The equality of 1 mole = 22.4 L is the basis for the conversion factor.
