3. Ethanol has a density of 0.800 g/mL. <br> a. What is the mass of 225 mL of ethanol?
dedylja [7]

Since the ethanol has a density of 0.800 g/mL, the mass of the ethanol is 180 grams.

<u>Given the following data:</u>

  • Volume of ethanol = 225 mL
  • Density of lead ball = 0.800 g/mL.

To find the mass of the ethanol;

Density can be defined as mass all over the volume of an object.

Mathematically, the density of a substance is given by the formula;

Density = \frac{Mass}{Volume}

Making mass the subject of formula, we have;

Mass = Density \times Volume

Substituting the given parameters into the formula, we have;

<em>Mass of ethanol </em><em>=</em><em> 180 grams.</em>

What happens when the vapor pressure of a liquid is equal to the external pressure? The liquid freezes The intermolecular forces
Makovka662 [10]

Answer:

The liquid boils.

Explanation:

Vapor pressure is simply defined as the pressure exerted on a substance (solid/liquid) by the vapor of the substance collected just at the top of the surface of the substance. In concise words, it is the pressure of Vapor that is in contact with its solid or liquid state.

For a liquid, it is the pressure of the Vapor gathering at the top of the surface of the liquid.

When this Vapor pressure matches the external pressure, the temperature stays constant and the molecules of the liquid all through the liquid can gain enough energy, rise to the surface of the liquid and break free in gaseous form; thereby, boiling.

The definition of boiling point basically explains that it is the point at which temperature stays constant, and the vapour pressure of the liquid matches the atmospheric/external pressure around the liquid and its liquid molecules change into vapor.

This is why liquids boil faster at higher altitudes; the atmospheric pressure at higher altitudes is reduced, hence, the temperature at which liquid boils at this high altitude is normally lower than its known boiling point temperature.

It is also why food cooks to a temperature higher than the boiling point of water in a pressure cooker/pot. The added pressure ensures that the cooking water boils at temperatures higher than its boiling point; thereby exposing the cooking ingredients to a higher temperature, leading to faster cooking.

Hence, it is obvious why boiling is the answer to this question.
