Diluting concentrated 1.74m acetic acid to prepare 200 ml of 8m stick solution. what volume of concentrated acid must be used

43.5 mL

Explanation:

We are given;

Molarity of dilute acetic acid is 1.74 M Volume of the solution that needs to be prepared is 200 mLMolarity of the stock solution 8 M

We are required to determine the volume of acid that must be used.

We need to know the dilution formula;According to the dilution equation;

M1V1 = M2V2

Rearranging the formula;

V1 = M2V2 ÷ M1

   = (1.74 M × 200 mL) ÷ 8 M

   = 43.5 mL

Therefore, the volume of the concentrated acid that must be added is 43.5 mL

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
