A certain solution has an osmotic pressure of 17. atm at 357 K. The molar concentration, calculated as (c = π / R × T) is 0.58 M.
<h3>What is osmotic pressure?</h3>
Osmotic pressure is a colligative property of solutions. It can be calculated as the product of the molarity of the solution, the ideal gas constant (R), and the absolute temperature.
π = c × R × T
where,
- π is the osmotic pressure.
- c is the molarity of the solution.
- R is the ideal gas constant.
- T is the absolute temperature.
A certain solution has an osmotic pressure of 17. atm at 357 K. We can calculate the molar concentration as follows:
c = π / R × T
c = 17. atm / (0.0821 atm.L/mol.K) × 357 K = 0.58 M

Secondary structure is provided by hydrogen bonds between atoms in the polypeptide backbone of proteins. Interactions between the side chain atoms of the amino acid subunits form the conformation.
The secondary structure consists of local packing of the polypeptide chain into α-helices and β-sheets by hydrogen bonding between the peptide bond and the central carbon backbone. Tertiary (3D) structure is the shape that results from secondary structural folding determined by interactions between amino acid side chains.
Secondary structure results from hydrogen bonds that form between atoms in the polypeptide backbone. A hydrogen bond is formed between a partially negative oxygen atom and a partially positive nitrogen atom.
The tertiary structure is stabilized by side chain functional groups including several interactions, especially hydrogen bonds, salt bridges, covalent disulfide bonds, and hydrophobic interactions.

Answer:
The minks are very high on the aquatic food chain. The mink is a carnivorous animal, which means it eats only meat.
Explanation:
[AR] 3d10 4s2 is the configuration for zinc
<span>First we can calculate the area of the rectangular lawn using the formula:
Area = Width x Length = 21 ft x 20 ft = 420 square feet
And the total number of snow flakes per minute on the entire lawn is:
(1350 snowflakes per minute per square foot) x (420 square feet) = 567,000 snowflakes per minute
In one hour (or 60 minutes) we get a total of:
(567,000 snowflakes per minute) x (60 minutes / 1 hour) = 34,020,000 snowflakes
The total mass of which would be:
34,020,000 snowflakes x 1.60 mg = 54,432,000 mg = 54.432 kg (as 1 kg = 1,000,000 mg).
So 54.432 kg of snow accumulates every hour on the lawn.</span>
