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.
