How many grams of solute are needed to make 250 mL of a 2.055 M NaCl solution?
Veronika [31]

Answer:

30grams

Explanation:

To calculate the mass (number of grams of the solute) in the solution, we need to calculate the number of moles it contains first. We use the formula;

M = n÷ V

Where; M= Molarity or Molar concentration = 2.055M

n= number of moles= ?

V= Volume = 250mL

Volume in L is 250/1000 = 0.250L

n= M × V

n= 2.055 × 0.250

n= 0.51375moles

The mass is calculated using :

Mole (n) = mass (m) / molar mass (MM)

Molar mass of NaCl = 23 + 35.5

= 58.5g/mol

Mass = molar mass × mole

Mass = 58.5 × 0.51375

Mass = 30.0543

Therefore, the mass is 30grams

Apa template about multiple sclerosis
garik1379 [7]

Answer:

Multiple Sclerosis is an inflammatory disease in which myelin sheath of nerve cells of brain and spinal cord are damaged.

Explanation:

Cause:- (Exact cause of inflammation is not known)

  • But damage is caused due to attack by autoimmune cells or antibodies against myelin sheath.

Types of tissues attack:-

  • Oligodendrocytes and myelin sheath is damaged and stripped away from axon and the process is known as demyelination.
  • Myelin sheaths are made up of fatty tissues and help in transmission of electric impulse.

Result of immune system attack:-

  • Damaged myelin sheath stop forming whIte matter of central nervous system.
  • Hence disrupt coordinating communication between different brain regions.

Signs and symptoms:- vary from person to person

  • Diminished eyesight.
  • Disrupt motor coordination.
  • Weak sensory perception.
  • Fatigue and dizziness.
  • Speech disorder.
  • Muscle weakness and spasticity.
  • Difficulty in urination and stool.

Diagnosis and treatment:-

  • Diagnosis include MRI T2 findings and cerebrospinal fluid specific oligoclonal bands.
