Describe the particles of a solid, liquid, and gas. For each, be sure to tell how far apart they are and how fast or slowly they
Art [367]

Answer:

Solid

  • A solid is a state of matter where the particles are tightly packed together, they are very close together
  • They vibrate, they move very slowly

Liquid

  • A liquid has free-flowing particles, but they may not leave the container
  • They move at medium speed

Gas

  • <u><em>A gas moves very freely, they leave the container, and they may not be captured in its entirety</em></u>
  • <u><em>It moves very fast because it is heated</em></u>

<u><em></em></u>

Hope this helps :)

A 125-mL sample of an aqueous solution of the protein ovalbumin from chicken egg white contains 1.31 g of the dissolved protein
Stella [2.4K]

The molar mass of the protein is 45095 g/mol.

The mass of a sample of a chemical compound divided by the quantity, or number of moles in the sample, measured in moles, is known as the molar mass of that compound.

The expression of molar mass of protein is

M₂ = (W₂/P) (RT/V)

Given;

W₂ = 1.31g

P = 4.32 torr = 5.75 X 10⁻³ bar

R = 0.083 Lbar/mol/K

T = 25°C = 298.15 K

V = 125 ml = 0.125 L

Putting all the values in the above formula

M₂= (1.31 g/5.75 X 10⁻³ bar) X (0.083 Lbar/mol/K X 2)/0.125 L)

M₂ = 45095 g/mol

Thus, the molar mass of the protein is 45095 g/mol.
