3.2. Dimensions in Chemical Engineering

Try these first

1. 1.

   Define mass concentration.

   Hint

   Think about the units of mass and volume.

2. 2.

   What does the prefix Rho (ρ) indicate?

   Hint

   It is a symbol used when discussing concentration.

3. 3.

   What is the symbol for mass concentration?

   • A: C
   • B: ρ
   • C: M

   Hint

   Think about densities in formulas.

4. 4.

   True or False: Vapour pressure is related to a substance's concentration in water.

   • True
   • False

   Hint

   Reflect on the relationship between phases.

5. 5.

   Calculate the concentration of a chemical in the air if its concentration in water is known to be 10 g/L and the partition constant for air to water is 0.5.

   Hint

   Remember the partition constant formula and how to manipulate it.

6. 6.

   Discuss how varying soil organic content affects the partitioning of a hydrophobic chemical.

   Hint

   Focus on organic matter's role in chemical interactions.
