Answer:

a liquid with weak intermolecular forces and a high temperature

Explanation:

According to encyclopedia Britannica, "Vapour pressure is a measure of the tendency of a material to change into the gaseous or vapour state, and it increases with temperature. The temperature at which the vapour pressure at the surface of a liquid becomes equal to the pressure exerted by the surroundings is called the boiling point of the liquid."

This implies that the vapour pressure of a liquid tends to increase as the temperature of the liquid increases. Recall that vapour pressure also depends on the magnitude of intermolecular forces. The greater the magnitude of intermolecular forces, the lower the vapour pressure hence water has very much higher vapour pressure than ethane.

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>
