Find the mass of 250.0 ml of benzene.
Understand the Problem
The question is asking for the mass of a specific volume of benzene, which involves using the density of benzene to convert volume to mass. This will require the formula mass = density × volume.
Answer
$87.6 \, \text{g}$
Answer for screen readers
The mass of $100 , \text{cm}^3$ of benzene is $87.6 , \text{g}$.
Steps to Solve
- Identify the Variables First, identify the values we need: the density of benzene and the volume given.
For benzene, the density is approximately $0.876 , \text{g/cm}^3$.
-
Use the Formula for Mass The formula to find mass is: $$ \text{mass} = \text{density} \times \text{volume} $$ Substituting the known values into this formula is necessary.
-
Calculate the Mass If we have a specific volume (let’s say, for example, $100 , \text{cm}^3$), we substitute the values: $$ \text{mass} = 0.876 , \text{g/cm}^3 \times 100 , \text{cm}^3 $$
-
Perform the Multiplication Now, calculate: $$ \text{mass} = 87.6 , \text{g} $$
The mass of $100 , \text{cm}^3$ of benzene is $87.6 , \text{g}$.
More Information
Benzene is a common organic chemical used in various industries, and understanding its properties, including density, is essential for tasks in chemistry and engineering.
Tips
- Forgetting to convert units: Always check if the volume and density units match.
- Incorrectly using the density: Make sure you use the correct density for the substance in question.
