The intermolecular forces or the strength of C is more than that of B.
What are intermolecular forces?
- Intermolecular forces are the forces that hold the molecules of any object in a particular state of matter.
- It exists between molecules.
- These forces are weak when compared with intramolecular forces.
- Hydrogen bonding, dipole-dipole, Vander Walls, and ion-dipole are the types of intermolecular forces.
- At a short distance, these forces are repulsive but at large distances they are attractive.
Here, we can see that C has dipole-dipole interaction while B has none.
Therefore, it states that the intermolecular forces present in C are much more than that in B.

Answer:
3.02× 10²⁴ atoms
Explanation:
Given data:
Number of nitrogen atoms = ?
Number of moles of N₂O = 2.51 mol
Solution:
1 mole contain 2 mole of nitrogen atoms.
2.51 × 2 = 5.02 mol
According to Avogadro number,
1 mole = 6.022 × 10²³ atoms
5.02 mol × 6.022 × 10²³ atoms / 1 mol
30.2 × 10²³ atoms
3.02× 10²⁴ atoms
Answer:
The answer is
<h2>69.30 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
volume = 42 mL
density = 1.65 g/mL
The mass is
mass = 1.65 × 42
We have the final answer as
<h3>69.3 g</h3>
Hope this helps you
Answer:
Specific gravity of mercury is 13.56 and it is an unit-less quantity.
Explanation:
Mass of the mercury = m = 607.0 lb = 275330.344 g
1 lb = 453.592 g
Volume of the mercury = v = 
Density of the mercury = d=
d = 13.56 g/mL
Specific gravity of substance = Density of substance ÷ Density of water
Specific gravity of mercury :
(unit-less quantity)
