I believe it is negative 1.
Molarity is the strength of the solution or the ratio of the moles and the volume of the solution. The molarity of the solution is 0.1516 mol per Liter.
<h3>What is molarity?</h3>
Molarity is the molar concentration of the solution that tells about the amount of the solute or the substance dissolved in the given amount of the solution.
Given,
- Mass of potassium chloride = 8.45 g
- Molar mass of potassium chloride = 74. 55 g/mol
- Volume of the solution = 0.750 L
Moles can be calculated by:

Calculate molarity by:

Substituting values in the equation:

Therefore, the molarity of the solution is 0.1516 mol per Liter.

Answer: The correct sequence for the series of event would be.
1. Igor's toe is being cut by the glass.
2. The wound surrounding the injury becomes infected with bacteria from Igor's foot.
3. Antibodies and circulating white blood cells stick to the bacteria creating a large complex in the lymph vessel.
4. The bacteria enter his lymph system and travel towards a lymph node.
5. The complex becomes trapped in a lymph node and is engulfed by a phagocyte.
6. The bacteria is destroyed.
Explanation:
Whenever there is any cut or wound in the body and body encounters invasion of the foreign materials it considers it as harmful pathogen.
These pathogens when enters the body it is considered as antigen, it then travels to the lymphatic system.
These bacterial complex is then killed by the phagocytes and digested by the body.
In this way the complex is killed and the bacteria is destroyed.
Ionic bond is formed by two opposite type of substances (metal and non-metal) while both covalent or metallic bond is formed by two same type of substances (non-metal and non-metal form covalent bond, metal and metal form metallic bond). Idk if it's true or not.
I think the best answer is that the spinal fluid surrounds and protects the backbone. Also, it protects the brain from trauma. It acts as a shock absorber. It supplies nutrients to the nervous system tissue and removes waste products from the brain.
