Cerebrospinal fluid of the central nervous system and synovial fluid of joint capsules are both examples of _______.
murzikaleks [220]

Cerebrospinal fluid of the central nervous system and synovial fluid of joint capsules are both examples of <u>extracellular </u><u>fluid</u>

  • Extracellular fluid called cerebrospinal fluid is present throughout the CNS
  • It acts as a protective layer for CNS ftom injury and shock
  • Cerebrospinal fluid is clear, colorless fluid produced by the choroid plexus.
  • It surrounds the brain and spinal cord.

Synovial fluid is a viscous solution found in cavities of synovial joints. The principal role of synovial fluid is to reduce friction between articular cartilages of synovial joints during movement.

  • Synovial fluid is a small component of transcellular fluid component of extracellular fluid.

What is the molality of a solution in which 0.42 moles aluminum chloride has been dissolved in 4200 water ?
madreJ [45]

Answer:

0.1 M

<h3>Explanation:</h3>
  • Molarity refers to the concentration of a solution in moles per liter.
  • It is calculated by dividing the number of moles of solute by the volume of solvent;
  • Molarity = Moles of the solute ÷ Volume of the solvent

<u>In this case, we are given;</u>

  • Number of moles of the solute, NH₄Cl as 0.42 moles
  • Volume of the solvent, water as 4200 mL or 4.2 L

Therefore;

Molarity = 0.42 moles ÷ 4.2 L

            = 0.1 mol/L or 0.1 M

Thus, the molarity of the solution will be 0.1 M
