A postulate of the kinetic molecular theory is listed. Postulate: Gas particles are in constant random motion.

Which of the following activities can be used to demonstrate the postulate?
Recording the change in pressure when heating an inflated tire
Observing the change in an inflated balloon when placed in cold liquefied nitrogen
Observing the ease of pushing the plunger of a blocked nozzle syringe containing gas
Recording the speed of colored gas spreading from one jar to an empty jar

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 

The answer to this problem is. 67

Density= mass/volume so 5.1 divided by 4.7 is  5.1 / 4.7 =1.08510638298round to the correct number of sig figs
