The mass of the alcohol sample is 587.46 g.
<h3>Density:</h3>
This is the ratio of the mass of a body and its volume. The S.I unit of Density is kg/m³
To calculate the mass of the alcohol we use the formula below.
Formula:
- D = m/V............... Equation 1
Where:
- D = Density of the alcohol
- m = mass of the alcohol
- V = volume of alcohol
make m the subject of the equation.
- m = DV................. Equation 2
From the question,
Given:
- D = 0.79 g/mL
- V = 743.62 mL
Substitute these values into equation 2
- m = (0.79×743.62)
- m = 587.46 g
Hence, The mass of the alcohol sample is 587.46 g.

Answer:
This is due to the relative melting points of the different layers (nickel–iron core, silicate crust and mantle) and the increase in temperature and pressure as depth increases We have the inner core, outer core, mantle and crust which play an important role on Earth.
The particles can undergo small oscillations around x₂.
The given parameters;
- <em>initial energy of the particles = E₁</em>
- <em>final energy of the particles, E₂ = 0.33E₁</em>
The movement of the particles depends on the kinetic energy of the particles.
When kinetic energy of the particles is 100%, the particles can oscillate from x₁ to x₅.
However, when the total energy of this particles is reduced to one-third (¹/₃) or 33% of the initial energy of the particle, the oscillation of the particles will be reduced.
- The maximum position the particle can oscillate is x₅
- The half position the particles can oscillate is x₃
Since 33% is less than the half of the energy of the particle, the particle will oscillate between x₁ and x₂.
Thus, we can conclude that the particles can undergo small oscillations around x₂.
