Answer:
M = 3.0 mol/L.
Explanation:
- We can calculate the molarity of a solution using the relation:
<em>M = (mass x 1000) / (molar mass x V)</em>
- M is the molarity "number of moles of solute per 1.0 L of the solution.
- mass is the mass of the solute (g) (m = 87.75 g of NaCl).
- molar mass of NaCl = 58.44 g/mol.
- V is the volume of the solution (ml) (V = 500.0 ml).
∴ M = (mass x 1000) / (molar mass x V) = (87.75 g x 1000) / (58.44 g/mol x 500.0 ml) = 3.0 mol/L.

The force of all gas particle/wall collisions divided by the surface area of the wall is the definition of pressure (P): One of the fundamental quantifiable variables of this phase of matter, pressure, is a property shared by all gases.

Answer:
0.65 M
Explanation:
Molarity (M) is the amount of moles of a substance per liter.
In other words, M = moles of substance / liters of solution
Since you're already given the moles of NaCl and the volume of the solution, you can plug those into the equation.
M = moles of NaCl / liters of solution
M = 1.5 mol NaCl / 2.3 L
M = 0.65 mol/L (or 0.65 M)
<span>Answer: option C. Refrigerant. When the fluid vaporizes(passes from liquid to vapor) absorbs a lot of energy (called latent vaporization heat) which causes that the surroindings cool. The latent vaporization heat of the fluid permits the refrigeration process and the fluid is the refrigerant, this is the substance that permit that the refrigeration process take place.</span>
Answer:
A tick living on a dog and drinking it's blood = Parasitism
Birds that live among cattle too eat insects stirred up by grazing = Mutualism
A clownfish living on the tentacles of an anemone provides nutrients too the anemone, and the clownfish is protected from predators = commensalism
A bear catching and eating a salmon from the river = predation
A bobcat catching and eating a rabbit = predation
A tapeworm living on the digestion system of a horse = parasitism
A Egyptian plover eating bugs off a giraffe or rhino = Mutualism
Bees gathering nectar and then spreading pollen too a flower = commensalism
