The correct answer is 0.038 but I need detailed steps how to get there. Thanks!

HI decomposes to H2 and I2 by the following equation:

2HI(g) → H2(g) + I2(g);Kc = 1.6 × 10−3 at 25∘C

a. 0.924 M
b. 0.076 M
c. 0.038 M
d. 0.0017 M

In many humans, exposing the skin to sunlight over prolonged periods of time results in the production of more pigment by the skin cells (tanning). this change in skin color provides evidence that -

Membrane vesicles containing an internal sodium chloride (nacl) concentration of 0.14 m are placed into separate beakers each containing a different solution. the first beaker contains 0.14 m sucrose, while the second beaker contains 0.14 m calcium chloride (cacl2). the temperature is 25°c. what is the solute potential inside the vesicles, expressed in units of mpa?
