The liquid that is expected to have the weakest intermolecular interaction is the liquid that has the lowest boiling point and surface tension.
<h3>What is boiling point?</h3>
The term boiling point refers to the temperature at which the atmospheric pressure and the pressure of the liquid becomes equal. The greater the intermolecular forces of attraction between molecules the higher the boiling point of the solid. Also a high surface tension indicates a strong intermolecular forces of attraction between molecules.
The liquid that is expected to have the weakest intermolecular interaction is the liquid that has the lowest boiling point and surface tension.

In order to calculate the experimental percent error, we follow these steps:
1- Subtract one value from the other (order does not matter as we take absolute)
2- Divide the obtained number by the accepted or true value.
3- Multiply the fraction you got from step 2 by 100 to get the percentage of error.
Now, we will apply these steps on our problem:
1- Subtract one value from the other:
9.95 - 7.13 = 2.82
2- Divide by accepted value:
2.82 / 7.13 = 0.3955
3- Multiply by 100 to get the error percentage:
error percentage = 0.3955 x 100 = 39.55%
Answer:
2.6 mole of lithium bromide have 225.81 g.
Explanation:
Given data:
Number of moles of lithium bromide = 2.6 mol
Mass of lithium bromide = ?
Solution:
Formula:
<em>Number of moles = mass/ molar mass</em>
Molar mass of lithium bromide = 86.85 g/mol
Mass = number of moles × molar mass
Mass = 2.6 mol ×86.85 g/mol
Mass = 225.81 g
Thus 2.6 mole of lithium bromide have 225.81 g.
