3. Ethanol has a density of 0.800 g/mL. a. What is the mass of 225 mL of ethanol?
1 answer:
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;
Making mass the subject of formula, we have;
Substituting the given parameters into the formula, we have;
<em>Mass of ethanol </em><em>=</em><em> 180 grams.</em>
