Which of the following liquids has the greatest viscocity? A. hexane (C6H14) B. CH3OCH2CH3 C. CH3CH2OCH2CH3 D. CH3CH2OH E. HOCH2
2 answers:
Answer: Option (A) is the correct answer.
Explanation:
Viscosity is defined as the ability of a liquid to resist its flow. When a substance has high viscosity then it is known as a viscous substance.
Also, more is the mass of a substance more will be its resistance to move from one place to another.
- Mass of hexane is 86.18 g/mol
- Mass of
is 60.09 g/mol
- Mass of
is 74.12 g/mol
- Mass of
is 40.06 g/mol
Mass of is 62.07 g/mol
Therefore, out of the given options viscosity of hexane is the greatest.
Answer:
E.
Explanation:
Hello,
In this case, the tendency to form hydrogen bonds (bridges) provides a substance more viscous character as long as the intermolecular forces strengthen, in such a way, the substance with the highest tendency to form the aforesaid bonds is the ethylene glycol, , due to its two hydroxiles in its structure.
Best regards.

The new volume at standard temperature and pressure is 5.08 L.
Explanation:
As per the kinetic theory of gases, the volume occupied by gas molecules will be inversely proportional to the pressure of the gas molecules. This is termed as Boyle's law.
So, pressure∝
Thus, if two pressure and two volumes are given then,
Now, we known the values of P₁ = 8 atm, V₁ = 635 mL, P₂ = 1 atm and V₂ we have to determine. We are considering P₂ = 1 atm, because we have to determine V₂ at standard temperature and pressure. And standard pressure is 1 atm.
Thus, the new volume at standard temperature and pressure is 5.08 L.
Answer:
2.32 m
Explanation:
So, according to definition of mole fraction:
Mole fraction = 0.176
Applying values as:
So,
Also, Molar mass of toluene = 92.14 g/mol
Thus,
The formula for the calculation of moles is shown below:
Also, 1 g = 0.001 kg
So,
Molality is defined as the moles of the solute present in 1 kg of the solvent.
It is represented by 'm'.
Thus,
<u>Molality of benzene = 2.32 m</u>
