Convert 190 mmhg to a) kilopascals
b) atmospheres

#a. 25.33 kPa

#b. 0.25 atmospheres

Explanation:Pressure may be measured using several units which include pascals, atmospheres, mmHg and kilopascals.These units of measuring pressure may be converted from one unit to another using a conversion factor.

For example;

1 kPa = 7.5 mmHg

Thus, in our case,

#a. To convert 190 mmHg to kPa

we divide 190 mmHg by 7.5 mmHg

   = 190 mmHg ÷ 7.5 mmHg

  = 25.33 kPa

Hence, 190 mmHg is equivalent to 25.33 kilopascals

Another conversion factor is;

1 atm = 760 mmHg

Therefore, in our case,

#b. To convert 190 mmHg to atmospheres

we divide 190 mmHg by 760 mmHg

That is; 190 mmHg ÷ 760 mmHg

            = 0.25 atm

Thus, 190 mmHg is equivalent to 0.25 atm

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
