What is the volume of .00831 mol of gas under ideal conditions if the pressure is 1.01 atm and the temperature is 25 degrees C?*

Approximately .

Explanation:

Convert the temperature of this gas to absolute temperature:

.

Let and represent the pressure and volume of this gas, respectively. Let represent the number of gas particles in this gas. Let represent the ideal gas constant. By the ideal gas law:

.

For this question:

(given,) (from unit conversion,) and.

Look up the ideal gas constant that takes as the unit for pressure:

.

This question is asking for , the volume of this gas. Rearrange the ideal gas equation and solve for :

.

For cyclohexane compounds drawn in a chair conformation:   -axial bonds are vertical  -equatorial bonds are parallel to two bonds within the ring.  thus, as i assume the chair conformation is drawn:   -the x group is in an axial position, as are the five other vertical bonds.  -three axial bonds are on the top face of the ring  -the other three axial bonds are on the bottom face  the position of the second substituent on each ring carbon is equatorial.  gauche groups must be on an adjacent carbon such as carbon 6 and carbon 2, and also gauche groups are rotated by 60 degrees relative to each other.  drawing the newman projections for c1–c2 and c1–c6 aids in visualizing the groups that are gauche to the y group on c1.  click this link and watch some academic videos that may you more understand the topic
