Assume human blood is iso-osmotic or isotonic with a 0.16 mol/lit saline (NaCl) solution (the solution does not change the volum

e of the blood cell) and for simplicity all dissolved salts in the solution are NaCl rather than ions. Estimate osmotic pressure at 37°C.

Answer:

π = 4.1 atm

Explanation:

We can calculate the osmotic pressure exerted by a solution using the following expression.

π = M . R . T

where,

π is the osmotic pressure

M is the molar concentration of the solution

R is the ideal gas constant

T is the absolute temperature

The absolute temperature is 37 + 273 = 310 K

π = M . R . T

π = (0.16 mol/L) . (0.082atm.L/mol.K) . 310 K = 4.1 atm

Which element is most likely to form a cation? <br> sodium, silicon, sulfur, argon
Harrizon [31]
<h3>Answer:</h3>

Sodium

<h3>Explanation:</h3>
  • To answer the question we need to know a few things.

What are cations?

  • Cations are positively charged ions that are formed when an atom of an element loses an electron(s).

What elements form cations?

  • Metallic elements form cations since they react by losing electrons thus forming ions with a positive charge.
  • For example, alkali metals such as sodium form cations with a charge of +1.
  • In this case, sodium will form a cation with a charge of + 1, Na⁺

What are negatively charged ions?

  • Negatively charged ions are known as anions.
  • They are formed by non-metallic elements such as sulfur, argon, silicon, etc.
