Steroids are biologically very important compounds. They are made up of more that seventeen carbons. The structure of Steroid is comprised of a fused cycloalkane ring system. The simplest steroid and the main skeleton of all steroids is Gonane.

Gonane is made up of four cycloalkane rings i.e. tetracyclic hydrocarbon ring structure. Among these four rings 3 are cyclohexanes (designated as A, B and C) and one is cyclopentane (Designated as D). These four rings fuse to form a <span>cyclopentaperhydrophenanthrene.

The Nucleus (Gonane) of steroids along with some derivatives are shown below,</span>

Nitrogen:0.781 oxygen:0.209 argon: 0.010 (Mole fraction)

horrorfan [7]

Answer:

The partial pressure of nitrogen is 597.5 torr

Explanation:

Step 1: Data given

Mol fraction of N = 0.781

Mol fraction of O = 0.209

Mol fraction Ar = 0.010

Atmospheric pressure = 765.0 torr

The partial pressure is given by Pi = Xi * Pt

⇒ χ i = the mole fraction of gas i in the mixture

⇒ P total = the total pressure of the mixture

Step 2: Calculate the partial pressure of nitrogen

P(N) = mol fraction of N * atmospheric pressure

P(N) = 0.781 * 765.0 torr = 597.5 torr

The partial pressure of nitrogen is 597.5 torr
