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>
