If 10.0 mL of blood plasma has a mass of 10.279 g and contains 0.870 g of protein, what is the mass/mass percent concentration o
Maru [420]

Answer:

Mass/mass percent concentration means the mass of the solute/mass of the solution times 100. You know both the mass of the solute (0.870 g protein) and the mass of the solution (10.279 g solution). So divide and multiply your result by 100.  (0.870 / 10.279 * 100)

Which of the following explains why water is a good solvent for polar and ionic compounds?
Anni [7]

Hi there!

<u>Electronegativity</u> is the concept of how likely an atom is to attract the shared molecules in one of these bonds to itself. We know the molecule water is made up of two hydrogens and one oxygen. The electronegativity of hydrogen is 2.2, and oxygen 3.4. An <u>ionic bond</u> needs at least a difference in electronegativity of 1.6. As the difference is less than that, we can say that water is a covalent molecule. This then wipes out choice B, because it is not ionic, and C, as we have seen it is actually covalent.

Now, we can see the difference in electronegativity between oxygen and hydrogen is still 1.2. This means that while it is not at the point for there to be an ionic bond, there is still a difference in attraction, where the electrons will tend to favor the oxygen more and 'hang around it' more. As electrons are <u>negatively charged</u><em><u>,</u></em> this means that the oxygen will gain a slightly negative charge. This then makes the molecule polar, because it now has a charge within the molecule. This means we have our answer, choice D.

In terms of hydrophobic molecules - they tend to be ones without a charge. (If you're interested in this kind of stuff, I'd search hydrophobic up, and possibly also look into hydrogen bonds).

Hope this helps! Feel free to ask me any other questions you have about this specific problem.

How would you compare the distance of the moon from earth and the distance of the sun from earth
love history [14]

One of them is smaller, because the moon is much closer to earth than the sun.

Think of the moon orbiting the earth as a smaller version of the earth orbiting the sun.
