Answer:

5.00 µM

Explanation:

Given data

  • Initial concentration (C₁): 250.0 µM
  • Initial volume (V₁): 1.00 mL
  • Final concentration (C₂): ?
  • Final volume (V₂): 50.0 mL

We can find the final concentration using the dilution rule.

C₁ × V₁ = C₂ × V₂

C₂ = C₁ × V₁ / V₂

C₂ = 250.0 µM × 1.00 mL / 50.0 mL

C₂ = 5.00 µM

The concentration of the diluted solution is 5.00 µM.

Which of the following factors will affect the freezing point of a solution?
erastovalidia [21]

The freezing point of the solvent in a solution changes as the concentration of the solute in the solution changes (but it does not depend on the identity of either the solvent or the solute(s) particles (kind, size or charge) in the solution).

Generally, pressures lower than 1 atmosphere lower the temperature at which a substance freezes, but for water, a higher pressure gives a lower freezing point. The force from a pressure change figures into the molecular forces already at play in a substance.

How is it possible to change the shape of your molecular models without breaking any of the covalent bonds?
horrorfan [7]

Answer:

A molecule's shape strongly affects its physical properties and the way it interacts with other molecules, and plays an important role in the way that biological molecules (proteins, enzymes, DNA, etc.) interact with each other.

Based on the mole ratios, what can most likely be predicted?
omeli [17]
From mole ratios, the mass ratio of different elements can be predicted. Also the volume can be predicted based on density for liquids and ideal gas law equation for gases. From the mole ratios, the empirical formula can be predicted, as well as the molecular formula given another data which is mass of the sample.
